Review decision

To resubmit, address

1. Reconcile receipt 2 citation: either label it as the 2011 journal publication (consistent with the DOI ycar.2011.02.012) or cite the primary JAMA 2010 paper (doi:10.1001/jama.2010.1735) and update the bundle to reflect that primary source.
2. Add receipt-grounded numeric results for both studies (post-operative AF frequency/incidence in receipt 1; primary endpoint result for time to recurrent symptomatic AF in receipt 2) or explicitly hedge to 'abstract did not report the effect estimate' rather than asserting direction.
3. Tighten the title to name the specific contrast, e.g., 'Prescription omega-3 in peri-operative CABG AF vs. recurrent symptomatic outpatient AF: a two-receipt evidence boundary.'
4. Soften 'surprising' to 'context-dependent' or similar — the peri-operative vs. outpatient distinction is well-established and the contrast is not paradoxical.
5. Remove the implication that receipt 2 'updates the picture' for receipt 1; clarify that the two receipts test the same compound in different populations and that the memo's signal is a heterogeneous cross-context contrast, not a direct contradiction.

Major issues

• Receipt 2 is mislabeled as 'JAMA 2010 RCT, Kowey et al.' in the prose; the bundle DOI and excerpt clearly identify it as published in a 2011 journal (ycar.2011.02.012), with the JAMA 2010 publication referenced secondarily. This is an internally inconsistent citation that undermines source-grounding trust.
• Receipt 1 is described as an 'OMEGA-3 POLYUNSATURATED FATTY ACIDS IN ATRIAL FIBRILLATION PREVENTION AFTER SURGICAL MYOCARDIAL REVASCULARIZATION' study; the abstract explicitly states the aim was to 'estimate an efficacy' in IHD patients pre-/post-CABG, but the excerpt does not provide the actual post-operative AF frequency results. The claim that receipt 1 'made it plausible that ω-3 PUFA can lower post-operative atrial fibrillation frequency' is therefore not directly receipt-grounded in the supplied excerpt — the effect estimate and its significance are absent.

Minor issues

• Title framing 'omega fatty acids atrial evidence boundary' is vague and does not name the specific intervention anchor (prescription omega-3) or the specific contrast (peri-operative CABG vs. outpatient recurrent symptomatic AF); readers cannot locate the signal from the title alone.
• Receipt 2's outcome claim ('no significant effect on time to recurrent symptomatic AF') is not directly supported by the supplied excerpt, which only states 'Limited data from small trials suggest omega-3 polyunsaturated fatty a[cid]' and does not include the trial's own result statement.
• The 'Why this is surprising' framing overstates the contrast: receipt 1 is a 2008 single-center 189-patient cohort, receipt 2 is a 663-patient multicenter RCT — the most natural reading is not 'surprise' but the well-known peri-operative vs. ambulatory AF distinction already documented in cardiovascular literature.

Reviewer note

The memo identifies a coherent and bounded contrast: prescription omega-3 in peri-operative CABG (receipt 1, 2008, 189 patients) versus outpatient recurrent symptomatic AF (receipt 2, JAMA 2010/Kowey et al., 663 patients). The signal — peri-operative benefit signal vs. null effect on recurrent symptomatic AF — is plausible and the alpha-memo's caveats about heterogeneity are appropriate. However, the memo (1) mislabels receipt 2's publication year and venue in the prose while the bundle metadata shows a 2011 journal, (2) does not supply the actual effect estimates from either receipt's abstract (receipt 1 excerpt cuts off before reporting AF frequency; receipt 2 excerpt is a JAMA context statement rather than the trial result), and (3) overstates the 'surprising' framing. These are fixable but material: the headline claim direction in each receipt must be receipt-grounded. Revise with the specified edits.
