Would you look for significances or reliability/reproducibility for 3 raters that measured radiographic lesions and classified them with 3 different scores (mirels Score, Harrington classification and Lodwick classification).

My colleague suggested to use Anova and t-test with p-values for everything to just go for statistically significant difference.

Edit: I used mostly ICC for a uniform analysis. kappa was just used for localisations (nominal)
