Short-course antibiotics for acute otitis media
Bibliographic record
Abstract
BACKGROUND: Otitis media is a common pediatric problem, for which antibiotics are frequently prescribed. OBJECTIVES: To determine the effectiveness of a short course of antibiotics (less than seven days) in comparison to a longer course (seven days or greater) for the treatment of acute otitis media in children. SEARCH STRATEGY: The medical literature was searched for randomized controlled studies of the treatment of ear infections in children with antibiotics published from January 1966 to July 1997. Search last updated March 1998. SELECTION CRITERIA: Studies were included if they met the following criteria: subjects one month to 18 years of age, clinical diagnosis of ear infection, no previous antimicrobial therapy and randomization to treatment with less than seven days versus seven days or more of antibiotics. DATA COLLECTION AND ANALYSIS: Data on treatment outcomes were extracted from individual studies, and combined in the form of a summary odds ratio. A summary odds ratio (OR) equivalent to one indicated that the treatment failure rate following less than seven days of antibiotic treatment was similar to the failure rate following seven days or more of antibiotic. MAIN RESULTS: The summary OR for treatment outcomes at eight to 19 days in 1,524 children treated with short-acting antibiotics for five days versus eight to 10 days was 1.52, 95% CI: 1.17-1.98, but by 20 to 30 days outcomes between treatment groups (n=2,115) were comparable (OR=1.22, 95% CI:0.98-1.54). The absolute difference in treatment failure (Random effects model RD=2.9%, 95%CI:-0.3% to 6.1%) at 20 to 30 days suggests that at minimum 17 children would need to be treated with the long course of short-acting antibiotics to avoid one treatment failure. Similarity in outcomes was observed for up to three months following therapy (OR=1.16,95% CI=0.9-1.5). Comparable outcomes were shown between treatment with ceftriaxone or azithromycin, and more than seven days of other antibiotics. REVIEWER'S CONCLUSIONS: This review suggests that five days of short-acting antibiotic is effective treatment for uncomplicated ear infections in children.

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.
