Significant findings between co-variables (upper part) and predictors (lower part) of diagnostic stability and the stability measures (panel A) and the number-of-hospitalisations (panel B). P-values are shown and the corresponding R2-values given in parentheses

^●Bi-variant analyses using the four stability measures as dependent variables and numbers-of-hospitalisations in combination with each of the putative co-variables or predictors of diagnostic stability as independent variables.

^◆Multiple regression with backward elimination using numbers-of-hospitalisations as the dependent variable and all the other co-variables and putative predictors as independent variables.
