Methods still require major revision. Administrative preregistration conditions do not determine this verdict.

Round 3 dispositions

Comment	Status	Assessment
C3-1	Partly resolved	Preference for survival estimates, extraction of missing follow-up, and sensitivity exclusions help. They do not justify interpreting incompletely observed event proportions as hazard ratios. Reason for declining revision is insufficient: previous proposal allowed censoring-aware synthesis, not mandatory exclusion whenever censoring occurs.
C3-2	Resolved	Identical component sets and thresholds now required within definition strata. Creatinine doubling separated from 50% eGFR decline; O50 follows corrected rule.
C3-3	Resolved	Shorter reference arms excluded from baseline estimation. Constant-hazard interpolation within observed follow-up is explicitly acknowledged. Separate new competing-risk problem remains below.
C3-4	Partly resolved	Separate pen and switching strategies now required. However, generic switching row remains an active node without specified switching threshold or algorithm.
C3-5	Partly resolved	Restricted sensitivities now rated separately; matching evidence sets required. New count-derived contribution method fails for zero-event arms.
C3-6	Resolved	PR04 and PR08 include O24C; narrative names both SMD outcomes.
C3-7	Resolved	Recurrent events use reported log rate ratios; count models require amendment.
C3-8	Resolved	O21 mapping now agrees with O21B. Other expanded composites excluded from pooling.
C3-9	Resolved	Comparator activation now requires identified molecule or procedure and class, without inappropriate numeric-dose requirement.

Major findings

Persistent: harms likelihood still does not handle censoring. protocol/protocol.qmd:464, “Event outcomes and harms.”

Calling counts a dichotomous outcome does not establish their subsequent hazard-ratio interpretation. Similar censoring distributions across arms are insufficient, even under proportional hazards. For example, complete-follow-up risks of 0.50 and 0.75 imply HR 2. With 20% independently censored immediately in each arm, recorded proportions become 0.40 and 0.60; their complementary log-log contrast implies HR 1.79. This example passes both proposed sensitivity cutoffs.

RoB assessment identifies uncertainty but does not repair the likelihood. Cochrane distinguishes known fixed-time event status from censored survival data. Cochrane Handbook, section 6.8

Replacement: “Use raw counts in a complementary log-log likelihood interpreted as a hazard ratio only when event status is known for all participants at a common within-trial horizon. Otherwise use reported or reconstructed survival contrasts or a likelihood accounting for censoring. Counts with unresolved incomplete observation may enter a separate sensitivity analysis of recorded harms, without hazard-ratio interpretation or fixed-horizon absolute-risk conversion.”

This preserves usable harms evidence while correcting the estimand.
New: contribution calculation is undefined for eligible sparse networks. protocol/protocol.qmd:823, “Confidence in cumulative evidence.”

Count-derived log hazard contrasts require differences of log(-log(1 − r/n)). This transformation is nonfinite when an arm has zero events or all participants experience events. No boundary correction, variance specification, or fallback is supplied.

Consider two trials: A versus B with 0/100 versus 10/100 events, and B versus C with 10/100 versus 0/100. This connected three-node network meets the 20-event rule, yet neither trial supplies a finite uncorrected contrast for the proposed inverse-variance contribution network. Dropping trials would recreate C3-5.

Replacement: “Auxiliary inverse-variance contribution matrices are used only when valid finite contrasts and standard errors are available for every contributing trial, with multi-arm covariance preserved. When this condition fails, within-study bias and indirectness are judged qualitatively across the full primary evidence set, with supporting studies and reasons recorded. A reduced auxiliary network must not be represented as the primary network’s contribution matrix.”

Any alternative numerical method needs an explicit zero-cell rule and justification before registration.
New: revised baseline-risk rule treats incompatible survival quantities as interchangeable. protocol/protocol.qmd:767, “Absolute effects.”

“Kaplan-Meier or cumulative incidence” does not specify how competing events are handled. For outcomes such as kidney failure or heart-failure hospitalization, death can preclude the event. One minus Kaplan-Meier survival with competing deaths censored differs from cumulative incidence accounting for those deaths. Cause-specific HRs and subdistribution HRs also cannot share an unspecified conversion rule. Competing-risks methods

Replacement: “Extract whether reported hazard ratios are cause-specific or subdistribution estimates and synthesize them separately. For outcomes with competing events, estimate absolute event probabilities using cumulative incidence. Convert cause-specific hazard ratios only through a model including both event and competing-event hazards; when required information is unavailable, report relative effects without absolute conversion. Subdistribution hazard ratios use a matching cumulative-incidence baseline. Kaplan-Meier complements must not substitute for competing-risk cumulative incidence.”

Minor finding

New: switching-strategy row lacks template protection. protocol/nodes.csv:97, IGLARLIXI_SWITCH_SC_TIT_QD; protocol/protocol.qmd:552, template activation rules.

is_template = no exposes a generic switching label as an eligible node despite missing strategy values. Narrative separation rule is appropriate, but table should enforce it.

Replacement values: node_id = IGLARLIXI_SWITCH_<strategy>_SC_TIT_QD; is_template = yes.

Replacement note: “Excluded from networks until a unique strategy identifier, permitted pens, switching threshold, and titration algorithm are specified. Each distinct strategy receives its own instantiated node.”

Add this third template category beside dose and comparator templates.

All requested materials reviewed. Table checks found no overlapping eligible windows or missing reference-SD or Turner mappings. Search renderer inspected statically; R execution was blocked by read-only temporary-file restrictions. No files changed.
