Low Target Attainment of Intravenous Cefuroxime in Critically Ill Term Neonates and Children: A Pooled Population Pharmacokinetics Study.
Article in Clinical pharmacokinetics, 2026. 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
BACKGROUND AND
objectiveCefuroxime is a widely prescribed beta-lactam antibiotic, particularly in pediatric cardiac and medical-surgical intensive care units. The aim of this study was to describe intravenous cefuroxime disposition in critically ill pediatric patients. Moreover, target attainment of currently applied dosing regimens was evaluated, and suggestions for improving these dosing regimens were provided.
methodsTwo datasets were pooled for population pharmacokinetic (popPK) analysis, using NONMEM version 7.5. To assess the optimal target attainment (> 90% of patients with 100% time [T] > [4×] minimal inhibitory concentration [MIC]
resultsThe cohort consisted of 45 pediatric patients with a median (interquartile range [IQR]) age of 391 days [31-3505] and body weight of 9.0 kg [5.0-29.8]. A two-compartment popPK model with first-order elimination and allometric scaling best described cefuroxime disposition. Intravenous cefuroxime clearance was estimated at 5.29 L/h/70 kg. Postnatal age and creatinine clearance (mL/min/1.73 m
conclusionsThese findings indicate that underexposure due to augmented renal function is possible when applying the current cefuroxime dosing regimens. Future research should focus on individualized dosing strategies to optimize cefuroxime exposure and efficacy in pediatric populations.
