*Values are no. (%) patients except as indicated. Data were missing for CD4+ T-cell count (372 patients), C-reactive protein (274 patients), and CT scan pattern (265 patients). PCP, Pneumocystis jirovecii pneumonia; IQR, interquartile range.
†Adherence to prescribed prophylaxis was unknown. Among already known HIV+ patients without prophylaxis and with available CD4+ T cell count (n = 74), median CD4+ T cell count was 33 cells/mm3 (range 12–85).
‡Defined as focal interstitial or alveolar consolidation.
§Defined as subpleural nodules, focal condensation, cavitation, or marked pleural effusion.
