Data are expressed as mean ± standard deviation, median (interquartile range), or n (%). COPD, chronic obstructive pulmonary disease; CHF, congestive heart failure; HIV, human immunodeficiency virus. To convert glucose from mg/dl to mmol/L, multiply by the factor 0.005. To convert lactate from mg/dL to mmol/L, multiply by the factor 0.111.
