AN: anorexia nervosa; COMP: comparison; R × C: rows and columns; 6-year: AN study 2 (6-year follow-up); 10-year: AN study 3 (10-year follow-up); 18-year: AN study 4 (18-year follow-up); 30-year: AN study 5 (30-year follow-up)
Raw data are situated in the middle of the table. Results of the initial omnibus test, a stratified Cochran–Mantel–Haenszel test for a singly ordered R × C table, are placed in the lower right corner. Results from the analyses for group differences, Kruskall-Wallis test, at each follow-up are placed to the right of the data. Below the data the analyses for trend within each group (AN or COMP) are shown (Linear-by-Linear Association test)
