The proportion of patients cured was similar in the two treatment
groups in the intention-to-treat population (80.3% in the clindamycin group and
77.7% in the TMP-SMX group; difference, −2.6 percentage points; 95% confidence
interval [CI], −10.2 to 4.9; P = 0.52) and in the populations of patients who could be
evaluated (466 patients; 89.5% in the clindamycin group and 88.2% in the TMP-SMX
group; difference, −1.2 percentage points; 95% CI, −7.6 to 5.1; P = 0.77). Cure rates did
not differ significantly between the two treatments in the subgroups of children,
adults, and patients with abscess versus cellulitis. The proportion of patients with
adverse events was similar in the two groups
