An evaluation of the empirical vancomycin dosing guide in pediatric cardiology.
Article in BMC pediatrics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundHigher doses of vancomycin are currently prescribed due to the emergence of bacterial tolerance and resistance. This study aimed to evaluate the efficacy and safety of the currently adopted vancomycin dosing guide in pediatric cardiology.
methodsThis was a single-center prospective cohort study with pediatric cardiac patients, younger than 14 years, from June 2020 to March 2021. The patients received intravenous vancomycin (40 mg/kg/day divided every 6-8 h) according to the department's vancomycin medication administration guide (MAG) for at least three days.
resultsIn total, 88 cardiac patients were included, with a median age of 0.82 years (IQR: 0.25-2.9), and 51 (58%) received cardiopulmonary bypass surgery (CPB). The majority (71.6%, n = 61) achieved a serum vancomycin level within the therapeutic range (7-20 mg/L). Infants, young children, and children exposed to CPB surgery had an increased incidence of subtherapeutic vancomycin levels, [7 (29.2%); P = 0.033], [13 (54.2%); P = 0.01], and [21 (87.5%); P = 0.009] respectively. After the treatment, 8 (10%) patients had an elevated Serum creatinine (SCr) and 2 (2.5%) developed acute kidney injury (AKI). However, no significant difference was found between the patients developing AKI or an elevated SCr and the group who did not, in terms of clinical, therapeutic, and demographic characteristics, except for the decreased incidence of SCr elevation in patients receiving an ACE inhibitor, [4 (36.4%); P = 0.036].
conclusionOur institution followed MAG recommendations; however, subtherapeutic serum concentrations were evident in infants, young children, and CPB patients. Strategies to prevent AKI should be investigated, as the possible causes have not been identified in this study.
