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
Background: Vancomycin infusion reaction (VIR) is a common adverse reaction to vancomycin. We aimed to investigate the effects of infusion rate, age, infusion time, renal function and history of allergy on the incidence of VIR. Methods: We conducted a single-centre retrospective cohort study with 153 patients (aged 0-92.7 years) who received a single intravenous dose of vancomycin for perioperative prophylaxis. Patients treated for active infections were excluded. Medical records were retrospectively evaluated for VIR occurrence, defined as itching, flushing or rash documentation. Results: VIR incidence was 46.7% (7/15) in patients aged <10 years, 47.4% (9/19) in those aged 10-20 years and 44.4% (4/9) in those aged 20-30 years, versus 2.7% (2/74) in those aged ≥60 years. Multivariable logistic regression identified younger age [adjusted odds ratio (aOR) 0.95, 95% CI 0.93-0.97] and higher weight-adjusted infusion rate (aOR 1.22 per mg/kg/h increase, 95% CI 1.04-1.43) as independent risk factors for VIR. Receiver operating characteristic analysis of the infusion rate by age group showed that the optimal cut-off value for patients aged 30-60 years was 14.8 mg/kg/h, whereas for those aged <30 years, it was 14.0 mg/kg/h. No patients developed VIR when the infusion rate was <9.4 mg/kg/h. Conclusions: Age and higher weight-adjusted infusion rate were key risk factors for VIR. Tailoring infusion rate to age and weight may reduce VIR incidence without unnecessarily prolonging administration time.
