Longitudinal changes of serum 25OHD levels in GCT patients (box plot image). Each box denotes the median 25OHD serum levels with interquartile ranges in cohorts at consecutive time-points. The connecting line demonstrates a decrease of levels reaching a nadir at the 6 months time point and subsequent rise of levels thereafter. Preop: preoperative measurement, post-op measurement after orchiectomy
