PRL and Stroke: We observed varying degrees of correlation of E and NE with F and 24-h UFC on day 1 post-stroke onset, with NE correlating most strongly with 24-h UFC (r = 0.54), 24-h UFC correlating negatively with TSH and PRL (r = −0.56, r = −0.43), and no significant correlation between catecholamines and pituitary hormones.
