Absolute lymphocyte counts and regulatory T cells. Sepsis patients who went on to develop persistent or nosocomial infection (gray bars) had lower absolute lymphocyte counts within 48 hours of sepsis onset (A) but not on day 7 of illness (B) compared with sepsis patients who recovered without infectious complication and healthy controls (A). No differences were seen among groups in percentage of regulatory T cells measured within 48 hours of sepsis onset (C) or over time (D). Bars (A, C) and symbols (B, D) represent median values, with error bars representing interquartile range throughout. Dashed lines and shaded areas (B, D) represent median and interquartile ranges for healthy control subjects (*P < 0.05; ***P < 0.001).
