CRP and pneumocystosis: The severe PJP group had significantly lower albumin (2.3 ± 0.4 vs. 2.6 ± 0.6 g/dL, P < 0.001), higher CRP (14.7 ± 9.0 vs. 7.6 ± 6.6 mg/dL, P < 0.001), and higher LD (median 407.0, IQR 296.0–532.0 vs. 325.0, IQR 245.8–407.3 IU/L, P = 0.005) levels than the non-severe PJP group.
