Table 1 : Age, body mass index (BMI) and prolactin levels, according to the etiology of hyperprolactinemia (n=138).


  Macroprolactinoma (n=46) Microprolactinoma (n=27) Other causes (n=65)

Age (years) 36.6 (±13.6) 34.6 (±12.7) 37.4 (±14.6)
BMI (kg/m2) 30.3 (±7.6) 27.6 (±5.6) 27.8 (±4.8)
Baseline prolactin (ng/mL) 200 (111-379)a 75 (39-149)b 56 (38-104)c
Maximum prolactin (ng/mL) 348 (198-1127)a 192 (108-260)b 76 (46-123)c

Age and BMI are expressed as mean ± standard deviation (SD), and prolactin as median and interquartile range.
Different letters indicate statistical difference: a ≠ b (p<0.001); a ≠ c (p<0.001); b ≠ c (p<0.001).
