07Draft from Evidence, Section by Section

Drafting feels like the central act of writing because it produces visible pages. In a controlled workflow, drafting executes decisions already made about purpose, audience, sources, governing requirements, Structure, and claims. This does not make drafting mechanical. It creates room for better judgment because the writer is not solving every project problem inside every sentence.^1,2

Start with the section contract

Before writing, read the section instruction and answer:

• What must the reader understand after this section?
• Which sources support it?
• Which source governs terminology or form?
• Which claims are planned?
• Which gaps or conflicts remain?
• What must not be introduced here?
• How long should it be?
• Which table or figure carries part of the message?

If these questions cannot be answered, the section is not ready. Return to the dossier or Structure instead of filling space.

Build a claim-evidence mini-plan

For each subsection, list the main claim, supporting source, material qualifier, and intended paragraph role. A simple plan might look like:

The plan makes it harder to write beyond the evidence. It also reveals when several sources support different parts of a sentence and should not be collapsed into one citation cluster.

Lead with the point

Readers often scan. Topic sentences let them follow the argument by reading the first line of each paragraph. The first sentence should normally state the paragraph's primary point; the rest supplies evidence, explanation, qualification, or transition.^1,3

Avoid openings that delay meaning with long scene-setting clauses. Put the important subject and action early. Keep related words close enough to prevent ambiguity. Use parallel structure when presenting comparable items. Repeat key terms when consistency helps more than stylistic variety.

Brevity comes from removing material that does not serve the reader, not merely from shortening words. A compact paragraph can still be dense. A longer paragraph can be clear if its logic is explicit. Readability is a property of information design as much as sentence length.

One paragraph, one main job

A paragraph can establish context, explain a method, report a result, compare evidence, interpret a finding, qualify a claim, or transition. When it tries to do all of these, the reader cannot tell which sentence controls.

Use a durable pattern:

1. Point
2. Evidence or explanation
3. Qualification or limitation where material
4. Connection to the next point

This pattern is flexible. Results paragraphs may lead with a finding and then provide magnitude and precision. Discussion paragraphs may lead with an interpretation, compare literature, consider alternatives, and end with the implication. The important discipline is that the paragraph's logic is visible.¹

Separate the levels of statement

Medical prose often blurs four different acts:

• Observation: What the study, source, or analysis reported.
• Interpretation: What the observation may mean.
• Implication: Why the meaning matters in a broader context.
• Recommendation: What somebody should do.

Each step requires additional support. A difference observed in a study does not automatically establish a causal explanation. A causal explanation does not automatically justify a practice recommendation. The farther the sentence moves from observation, the more carefully the writer must examine evidence, scope, and authority.^4,5

Signal the level with verbs. “Was associated with” does different work from “caused.” “Suggests” differs from “demonstrates.” “May inform” differs from “should change.” Do not use cautious verbs to disguise a fundamentally unsupported claim; qualification must be substantive.

Match strength to design and precision

Lack of statistical significance is not proof of similarity, a p-value alone is inadequate, and estimates and confidence intervals carry essential meaning.^6,7 The prose should reflect study design, effect size, precision, and limitations.

Randomization, blinding, comparator choice, sample size, follow-up, missing data, analysis populations, multiplicity, confounding, and exploratory analyses all affect what can be said. The writer does not need to become the statistician, but must understand enough to avoid changing the inference in translation.

Keep “significant” for contexts where its meaning is explicit. If you mean clinically important, say so and support the threshold. If you mean statistically significant, provide the result in the form expected by the project. If you mean notable, choose a less ambiguous word.

Preserve expected and unexpected findings

Documents often become distorted when they narrate only the anticipated result. Report findings in the order established by the objectives or Structure, including results that are null, negative, inconsistent, or difficult to explain. Give safety and tolerability appropriate space rather than treating them as an appendix to efficacy.^3,4

Unexpected findings do not need speculative explanation. State what occurred, confirm the analysis, inspect related evidence, and distinguish plausible explanations from demonstrated ones. A Discussion can acknowledge uncertainty without becoming weak. It becomes stronger when readers can see the boundary between result and interpretation.

Use quotations and paraphrases sparingly

Medical writing usually depends on synthesis rather than quotation. Paraphrase after understanding the source, not by changing a few words. Preserve the original meaning and scope. Cite the source supporting the idea. Direct quotations are appropriate when exact wording is itself material, but they should not substitute for analysis.

Plagiarism risk rises when writers work too closely from source sentences or reuse old documents without tracking origin. Copying previously published material, including one's own work, without appropriate attribution or permission is unethical even when it is unintentional.⁸ Draft from notes and claim plans, then verify against the source. Reused language should follow the project's permissions, disclosure, and originality requirements.

Draft with visible uncertainty

Use explicit query markers rather than silent guesses:

• [QUERY—The table labels this population FAS; the CSR text says ITT. Confirm preferred term.]
• [SOURCE NEEDED—Current practice statement lacks a full-text citation.]
• [AUTHOR INPUT—Alternative explanation for the unexpected safety pattern.]
• [STATISTICAL REVIEW—Confirm wording of noninferiority conclusion.]

Queries are not signs of failure. They are evidence that the document is under active control. Remove or resolve every marker before finalization; do not let uncertainty vanish merely because the prose around it sounds complete.

Review the section before moving on

At the end of a section, perform a short review:

• Does it fulfill the section instruction?
• Does every material claim have the right support?
• Are numbers and populations consistent with sources?
• Are observation and interpretation separated?
• Are limitations and uncertainty proportionate?
• Is any information duplicated elsewhere?
• Does the last sentence hand the reader to the next section?

Early section review catches conceptual drift before it spreads into the abstract, summary, visuals, and conclusion.
