For patients with CD4 counts below 200/mm?3 the baseline probabilities according to three CD4 levels (101-200, 52-200, 0-50) were as follows:
Primary fungal infection (0.0026, 0.0039, 0.0060);
survive fungal infection (0.8, 0.8, 0.8);
other opportunistic infection (0.037, 0.0434, 0.93);
survive other opportunistic infection (0.7, 0.7, 0.7);
fungal relapses (0.0043, 0.0043, 0.0043);
fluconazole efficacy (0.7, 0.7, 0.7);
chronic AIDS death (0.0, 0.0070, 0.068);
non-AIDS death (0.00071, 0.00071, 0.00071);
CD4 decline from 101-200 to 51-100/mm?3 (0.047, NA, NA);
CD4 decline from 51-100 to 0-50/mm?3 ((NA, 0.0917, NA).
These values were used as the baseline inputs to the Markov model. For sensitivity analysis each parameter was tested over a plausible range.
