What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAntimicrobial resistance (AMR) is a major global health threat driven by inappropriate antibiotic use. There is a lack of region-specific prescribing data from India. The primary objective of this study was to assess the appropriateness of antibiotic prescribing using standardized clinical vignettes. The secondary objectives were to evaluate factors influencing prescribing decisions and practitioners' attitudes toward antimicrobial stewardship among medical practitioners in Karaikal, Puducherry, India.
methodsA cross-sectional study was conducted among 192 practitioners using eight validated clinical vignettes (1,536 prescribing decisions). The appropriateness of prescribing was assessed using national and international guidelines. The influencing factors and stewardship attitudes were evaluated using a five-point Likert scale. Statistical analyses included chi-square tests for categorical variables and Pearson correlation and multivariable linear regression for the total vignette score.
resultsThe overall prescribing appropriateness across the eight clinical vignettes was 57.2% (879 of 1,536). Overprescribing was most frequent for physiological leukorrhea, herpes zoster, asthma exacerbation, and upper respiratory tract infection (URTI). Higher appropriateness was observed among superspecialists, government/dual-sector doctors, and those with greater than 10 years of experience (p < 0.001). Experience greater than 10 years has independently predicted appropriateness. Strong support for antibiotic stewardship was also observed.
conclusionPrescribing appropriateness improved with seniority, pointing out the need for targeted Continuing Medical Education (CME), guideline dissemination, and stewardship interventions to address AMR.
