Correlation of transdiaphragmatic twitch pressure to blood urea nitrogen, albumin, and glucose levels. Transdiaphragmatic twitch pressure (PdiTw) as a function of (A) blood urea nitrogen (BUN), (B) albumin, and (C) glucose levels. There was no significant correlation between any these parameters and PdiTw. Specifically, correlation coefficients and P values for regression of PdiTw to parameters were, respectively, 0.146 and 0.277 for BUN, 0.072 and 0.596 for albumin, and 0.032 and 0.815 for glucose levels (all nonsignificant).
