No treatment effect: p<0.05 with Welch's t-test on recorded values 5.1%, Mann-Whitney 4.8%, log-rank 6.7%, log-normal AFT 7.4%; treated mice censored 7.2%; median estimated latency ratio (AFT) 0.99; mean recorded difference -0.1 s Treatment multiplies latency by 1.6: p<0.05 with Welch's t-test on recorded values 43.8%, Mann-Whitney 41.4%, log-rank 42.6%, log-normal AFT 50.9%; treated mice censored 24.9%; median estimated latency ratio (AFT) 1.60; mean recorded difference 12.0 s True mean difference without a cut-off in the second scenario: 18.0 s
