Multiple -squared: 0.3592. Hb was recoded into three levels according to values 11.5 and 12.5 based on its relationship with RVV. Levels of 1,25D were recoded into two levels according to their median in the subsample without missing values in the variables of the model. Hb: hemoglobin; 1,25D: 1α,25-dihydroxyvitamin D; P: serum phosphorus.
