Clarithromycin versus Amoxicillin alone or with Clavulanate in Acute Maxillary Sinusitis: A Meta-analysis of Clinical Trials
Bibliographic record
Abstract
Objective: A meta-analysis was performed to explore the relative effects of clarithromycin and amoxicillin (with or without clavulanate potassium) in the treatment of acute maxillary sinusitis. Methods: Six studies were identified in the peer-reviewed literature. All were randomized single-blind (investigator-blind) or open-label trials in outpatients diagnosed with acute maxillary sinusitis. A total of 1580 patients were enrolled, of whom 1194 were clinically evaluable. The total daily dose of clarithromycin was 1000 mg; the total daily dose of amoxicillin (with or without clavulanate potassium) was either 1500 or 2000 mg. The duration of study drug treatment varied from 8 to 14 days. Endpoints comprised clinical and radiological success within 48 h of the end of study drug treatment plus bacteriologic cure and eradication. Success and cure rate differences were analyzed using fixed- and random-effect models. The absence of between-study heterogeneity was tested using Cochran’s Q-test. Results: Clinical success rates varied between 85.8% and 97.9% for clarithromycin and between 84.2% and 96.8% for amoxicillin. The combined rate difference in clinical success rates between clarithromycin and amoxicillin was +1.9% (P=0.14). Radiological success rates (four studies) varied from 78.2% to 94.0% for clarithromycin and 79.7% to 95.0% for amoxicillin, with a combined rate difference of zero (P=1.00). Bacteriologic cure rates (four studies) were 87.1–94.6% for clarithromycin, compared with 89.8–98.1% for amoxicillin, with a combined difference in cure rates of –3.2% (P=0.16). Overall bacterial eradication rates were comparable between the two treatments (clarithromycin, 89.3%; amoxicillin, 92.1%). Conclusion: These data, with their limitations properly acknowledged, identify clarithromycin as a valid and viable alternative to amoxicillin for the treatment of acute maxillary sinusitis in adults.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
