Abbreviations: CI, confidence interval; IRR, incidence rate ratio.

^a Confidence intervals were adjusted to ensure a false discovery rate of ≤0.05 and correspond to a marginal confidence level of 99.25%. See Methods and Web Appendix 3.

^bq values, which represent the minimum false discovery rate if the threshold for declaring significance includes a parameter, were estimated via the Benjamini and Hochberg procedure (Web Appendix 3).

^c Proportion of parameter estimates more extreme than the observed value under 10,000 permutations of end dates for each gathering and gathering sets between villages.

^d Number of village-weeks in exposure category.

^e The reference group is the set of village-weeks in which no gathering was hosted 0–3 weeks prior.
