Number of cases (and percentage of total cases) in which a model fit significantly better than an alternative model by the F ratio test in the study participants

  • n = 55. Two-sided P values were calculated by the binomial proportions test for the proportion of times the first model was selected over the second model in comparison to the number of selections expected.
