GPT and susceptibility to pneumonia measurement: Elevated alanine aminotransferase levels (U per L) and lactose dehydrogenase (U per L) were observed in the symptomatic with pneumonia group compared with the symptomatic without pneumonia group (21.3 [IQR, 15.0–30.4] vs. 17.7 [IQR, 11.7–24.7] and 177.1 [IQR, 145.6–221.0] vs. 155.7 [IQR, 138.5–173.5], respectively) (Table 2).
