Data are presented as mean (SD) or count (%), as appropriate. β coefficients (95% CI) represent the differences between the treatment groups and standard treatment (dexamethasone) in the WCS at the follow-up assessment and were calculated by using linear regression adjusted for age, baseline WCS, and study center. ORs (95% CI) were calculated by using logistic regression (recovered and improved) or ordinal regression adjusted for age, baseline WCS (as appropriate), and study center. P values were calculated by using linear regression, logistic regression, or ordinal regression, in line with coefficient reporting. —, not applicable.
