risk of death, 98.9% lower, RR 0.01, p = 0.60, treatment 0 of 6 (0.0%), control 91 of 599 (15.2%), continuity correction due to zero event (with reciprocal of the contrasting arm).

prioritizing more serious outcomes. For an individual study the most serious

however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.
