ED, eating disorders; AD, affective disorder; AP, asthma pathology; NP, non-pathology group; N, sample size; M, mean; SD, standard deviation; OR, odds ratio; Individual correlate, conditional logistic regression for each variable. Stepwise model selection, selected correlates for the model using AIC indices (empty cells mean that the variable was excluded in the model).
az-value is statistically significant, but its statistical significance was corrected for multiple comparisons.
tp < 0.10.
*p < 0.05;
**p < 0.01.
Statistical significance of individual correlates was corrected using Holm–Bonferroni correction for multiple comparisons.
