Events as n (6000 vs 6000 events): Welch's t-test p = 1.9e-24 Per-mouse arithmetic mean (6 vs 6 mice): KO / WT 0.82, Welch's t-test p = 0.28 Per-mouse median, log scale, ignoring day: KO / WT 0.84 (95% CI 0.57 to 1.26), p = 0.37 Per-mouse median, log scale, staining day as a block: KO / WT 0.84 (95% CI 0.74 to 0.97), t(8) p = 0.02 Per-day WT median fluorescence (mean of the two WT mice): day 1 2288; day 2 1141; day 3 2002
