Case Study 1 — Hernandez Writes an Approach That Pre-empts Its Critics
Composite, for teaching. Figures and methods are illustrative.
The Situation
Dr. Hernandez must write the approach for her diabetes-adherence trial — the longest, most scrutinized section. She has a sound design, but her instinct is to present it as airtight, hiding the parts she's worried about. This chapter tells her to do the opposite: spend her detail strategically and name her own weaknesses before the study section does.
Applying the Chapter
She structures by aim. Each of her three aims gets a parallel sub-section — restate the aim, give the rationale, present the plan, state expected outcomes, address pitfalls. A reviewer can verify, aim by aim, that every promise from her aims page (Chapter 6) has a credible plan. The structure also reinforces coherence: the approach visibly delivers the aims.
She spends detail where the risk is. Hernandez resists the wall-of-methods temptation. Standard consent and data-entry procedures get a sentence each, with a citation to her prior work. But the two genuinely tricky parts — how adherence will be measured (a method with known reliability issues) and how she'll handle missing data — get full, careful paragraphs. A reviewer skimming sees instantly where she has invested thought, and trusts that she knows which parts are hard.
She deploys preliminary data against the doubt. The study section's likely worry is whether her automated measurement actually works at scale. So she features the pilot result that shows exactly that — "these data (Figure 1) demonstrate that the automated method reliably captured adherence in 40 participants, with [agreement] against the reference standard" — placed precisely where the doubt lives, then moves on. She does not pad the section with every pilot finding; she uses the two that answer feasibility doubts and gives the floor to the plan.
She pre-empts her real weaknesses. Hernandez identifies her two genuine risks: recruitment might lag, and the measurement might have high missingness. For each, she writes a pitfalls-and-alternatives passage. Recruitment: "Should enrollment lag at the 6-month milestone, we will activate our second partner clinic, whose letter confirms access to [N] additional eligible patients." Missingness: "Should missingness exceed [threshold], our analysis plan specifies [method], and we will [sensitivity analysis]." She takes the study section's two strongest objections and answers them before they can be raised.
The Trap She Avoids
Hernandez's first draft hid the missing-data risk entirely, presenting the measurement as flawless. Her mentor, playing skeptic (Chapter 4), immediately asked "what about missingness with that method? Your reviewers will." Had she submitted the hidden version, a reviewer would have found the weakness alone and marked it as an unaddressed flaw — and possibly as naivety, since the issue is well known. By naming and addressing it, she converted a reason to reject into evidence that she understands her method deeply.
The Payoff
Hernandez's approach reads as the work of someone who has done this kind of study: strategic detail, evidence placed against doubt, and her two real risks disarmed. When her assigned reviewer presents it, the obvious objections ("but what about recruitment? missingness?") are already answered on the page, leaving the reviewer to advocate rather than attack. The approach earns the belief that significance alone cannot.
Discussion Questions
- Hernandez's mentor caught a hidden weakness by playing skeptic. Why is this the single most valuable use of a critical reader for the approach section?
- She gave one sentence to consent and a full paragraph to the measurement method. What does that allocation tell a reviewer, beyond the content itself?
- Trace how a hidden weakness, discovered by a reviewer, becomes "naivety or evasion," while the same weakness disclosed becomes "sophistication." Why the asymmetry?
