Impact of the current GC dose on the lowest (min) T-score in all patients in linear regression using (1) a crude model only including GC categories; (2) a multivariable model adjusted for age, sex, menopause, body mass index, alkaline phosphatase, disease duration, bisphosphonates and denosumab; and (3) a multivariable model specifically adjusted for the variables that emerged in the data mining process and were confirmed with backward selection for the respective T score (compare online supplemental table S5). The regression coefficient β and respective 95% CIs are shown. Significant coefficients are highlighted in red. The size of the boxes indicates the case numbers, also shown in brackets, of the respective groups; these are the rounded pooled case numbers of the 10 imputed data sets. For ‘no GC’ as the reference group, no coefficient was estimated. GC, glucocorticoid.
