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 AND
objectivesThe relative contribution of vancomycin exposure versus clinical factors to acute kidney injury (AKI) development in pediatric patients remains unclear. This study examined risk factors for AKI in pediatric patients receiving intravenous vancomycin therapy, with particular focus on elucidating the role of vancomycin concentrations and evaluating the safety implications of recent dosing guideline changes published in 2020.
methodsFor this retrospective cohort study, Texas Children's Hospital database was queried between 2011 and 2019 for demographics, concomitant medications, vancomycin dosing and levels, serum creatinine, and mortality. AKI was defined using modified KDIGO criteria. Empirical Bayesian forecasting with a published population pharmacokinetic (PK) model generated rich PK profiles from sparse sampling data. Multivariate logistic regression was used to identify risk factors, and simulations were performed to evaluate 2020 guideline recommendations.
resultsThe final analysis dataset included 2318 vancomycin courses in 1714 unique patients. The typical dosing regimen in our dataset was 45 mg/kg/day every 8 h. AKI occurred in 18.9% of patients. Independent risk factors included lower age, ICU residence, vasopressor administration, concurrent piperacillin/tazobactam, and amphotericin B use. While vancomycin 24-h area under the curve (AUC
conclusionsClinical factors are substantially more predictive of AKI than vancomycin exposure in pediatric patients. Given the questionable clinical necessity for increased dosing based on low mortality rates, prospective studies incorporating clinical efficacy endpoints are needed to establish optimal dosing strategies that balance therapeutic benefit with nephrotoxicity risk.
