NPPB and susceptibility to pneumonia measurement: While the median glomerular filtration rate was higher, and some prognostic markers (lymphocyte counts, Interleukin-6 (IL-6), D-dimer (DD), Troponin T (TnT), and Brain natriuretic peptide (BNP) levels) were more favorable among Latin Americans, there was a trend toward a higher frequency of extensive pneumonia (>50% of opacities in lung surface on X-rays) among them (33.3% vs. 23.5%, p = 0.09).
