Figure 1. Changes in six pituitary hormones over time in patients with different histological types (n = 81).

Box plot consists of median (middle line), the P²⁵ (bottom of the box) and the P⁷⁵ (top of the box) percentiles. Log transformation was preceded prior to doing analysis. Data were tested by generalized estimation equation (GEE). ^a-c significantly different from baseline ^a, postoperative day 1 ^b, or postoperative day 7 ^c, P < 0.05. * significantly different from the GnH type, P < 0.05. † significantly different from the PRL type, P < 0.05. § significantly different from other types, P < 0.05.
