NPPB and Pleural effusion: Patients with hypocalcemia had higher levels of NT-proBNP (P = 0.006), and there were no significant differences between groups in terms of troponin T. RV dilation was significantly more common (110 [48.5%] vs. 132 [38.8%], P = 0.023), and pleural effusion tended to be more common (244 [72.6%] vs. 257 [55.4%], P < 0.001) in the hypocalcemia group than in the control group.
