jc.2019-01375 Supplemental Tables

Supplemental Table 1. Predicted hormone level 95% confidence intervals for age (1-year increments) based on manuscript Figure 1, panels a-d. Due to small number of samples in the tail ends of the dataset, satisfactory reference intervals for ages 6 and 15 years could not be determined. Supplemental Table 2. Predicted hormone level 95% confidence intervals for orchidometer testicular volume (1-ml increments) based on manuscript Figure 2, panels a-d. The model was unable to determine accurate reference intervals for the tail ends of the dataset due to small sample sizes. Abbreviations: orchidometer testicular volume, TVOM; ultrasound testicular volume, TVUS.
