control: mouse median scores 0: 0, 1: 1, 2: 4, 3: 2, 4: 1; median of mice 2 treated: mouse median scores 0: 0, 1: 1, 2: 3, 3: 4, 4: 0; median of mice 2.5 A. Fields as n (72 vs 72), Mann-Whitney test: p = 0.26 B. Mouse scores treated as numbers, Welch t-test: mean 2.38 vs 2.38, p = 1 C. Mouse scores (8 vs 8), Mann-Whitney test: p = 0.91 D. Mean of the 9 field scores per mouse, Welch t-test: 2.19 vs 2.38, p = 0.67 E. Proportional-odds model of mouse scores: odds ratio for a higher score, treated vs control 1.18, likelihood-ratio chi2(1) = 0.03, p = 0.86
