Round 18: response to reviewers
Protocol version reviewed: 0.18.0. Revised version: 0.19.0.
Verdicts: GPT-6 Astra ACCEPT; Fable 5.1 ACCEPT; Grok 4.7 MINOR REVISION. GPT-6 Astra raised no comments. Grok 4.7 and Fable 5.1 raised the same two items. Every comment is answered below and recorded in ../comments.csv.
Correction to the round 17 response
The response to F17-4 deferred it because a new rule "would extend the revision beyond the comments of this round". F17-4 was a comment of that round, so the reason did not hold. The correct reason is that fixed time scenario inputs belong with the deferred reference arm likelihood work (F12-note, F16-note) in the same pre-analysis amendment (F18-0).
Summary of main changes
- Arm level known status for the binomial reference input, with an arm level 95 percent sensitivity analysis.
- Amendments pointer covers every comment whose action contains "deferred to amendment".
Grok 4.7 (grok-4.7)
G18-1 (minor; Absolute effects). The arm level f_a clause cited the trial wide complete status rule of the hazard ratio analysis.
Response (revised). Agreed; known status is the definition of the outcomes section applied to that arm alone rather than trial wide, and the sensitivity analysis uses the longest follow-up at which status is known for at least 95 percent of that arm, with unknown participants kept in the denominator as event free. fable-5.1 (F18-1) raised the same point.
G18-2 (minor; Amendments). The pointer matched only the exact action "deferred to amendment".
Response (revised). Agreed; the pointer now covers every row whose action field contains "deferred to amendment" (F12-note, F14-note, F15-note, F16-note, F17-4, F17-5). fable-5.1 (F18-2) raised the same point.
Fable 5.1 (fable-5.1)
F18-0 (note; Response record). The stated reason for deferring F17-4 did not hold on its own terms.
Response (corrected). Agreed; the reason should have been that fixed time scenario inputs belong with the deferred reference arm likelihood work (F12-note, F16-note) in the same pre-analysis amendment. The record is corrected here; the deferral itself is unchanged.
F18-1 (minor; Absolute effects). Cross reference after the arm level rule.
Response (revised). Agreed; see G18-1.
F18-2 (minor; Amendments). Scope of the Amendments pointer.
Response (revised). Agreed; see G18-2.
F18-3 (note; Absolute effects). A reported Aalen-Johansen value used directly has no stated one arm or pooling rule.
Response (deferred to amendment). Agreed that it belongs to the deferred F12-note matter and stays there.
