Input: We included 25 studies with a total of 2488 participants. Our primary outcome 'symptoms rated by participant or medical practitioner or proportion symptom-free' was commonly reported. No two trials examined the same drugs, therefore we grouped similar types of drugs together. Macrolides/streptogramins were found to be more effective than penicillin antibiotics (Risk ratio (RR) 0.84, 95% CI 0.73 to 0.97). In 3 trials involving 419 people, 2 of these studies used oral macrolide against intravenous (iv) penicillin demonstrating that oral therapies can be more effective than iv therapies (RR 0.85, 95% CI 0.73 to 0.98). Three studies with a total of 88 people comparing a penicillin with a cephalosporin showed no difference in treatment effect (RR 0.99, 95% CI 0.68 to 1.43). Six trials which included 538 people that compared different generations of cephalosporin, showed no difference in treatment effect (RR 1.00, 95% CI 0.94 to1.06). We found only small single studies for duration of antibiotic treatment, intramuscular versus intravenous route, the addition of corticosteroid to antibiotic treatment compared with antibiotic alone, and vibration therapy, so there was insufficient evidence to form conclusions. Only two studies investigated treatments for severe cellulitis and these selected different antibiotics for their comparisons, so we cannot make firm conclusions. We cannot define the best treatment for cellulitis and most recommendations are made on single trials. There is a need for trials to evaluate the efficacy of oral antibiotics against intravenous antibiotics in the community setting as there are service implications for cost and comfort.
Output:

We identified 25 randomised controlled trials. No two trials investigated the same antibiotics, and there was no standard treatment regime used as a comparison. We are not able to define the best treatment for cellulitis and our limited conclusions are mostly based on single trials. No single treatment was clearly superior. Surprisingly, oral antibiotics appeared to be more effective than antibiotics given into a vein for moderate and severe cellulitis. This merits further study. Antibiotics given by injection into a muscle were as effective as when given into a vein, with a lower incidence of adverse events. In one study the addition of corticosteroids to an antibiotic appeared to shorten the length of hospital stay, however further trials are needed. A single small study indicated vibration therapy may increase the rate of recovery but the results of single trials should be viewed with caution. We had insufficient data to give meaningful results for adverse events.
