  • a All women > all men (P = 0.01); no effect of AIDS status alone or interaction of gender and AIDS status on cell recovery (P > 0.05).

  • b Gender, AIDS status, or interaction between gender and AIDS had no significant effect on percentages of polymorphonuclear leukocytes (PMNs), lymphocytes, monocytes, or eosinophils in BAL fluid (for all, P > 0.05).
