Prevalence of acute kidney injury and nephrotoxic drug exposure in premature and low birth weight neonates admitted to intensive care units at Muhimbili National Hospital, Dar es Salaam.
Article in BMC pediatrics, 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
backgroundAcute kidney injury (AKI) poses a significant threat to premature and low birth weight (LBW) neonates in neonatal intensive care units (NICUs), driven by immature renal function and frequent exposure to nephrotoxic medications. Understanding its prevalence and risk factors is critical for improving outcomes in vulnerable populations.
objectiveTo determine the prevalence of AKI, exposure to potential nephrotoxic drugs and identify associated risk factors, among premature and LBW neonates admitted to NICUs at Muhimbili National Hospital (MNH), Dar es Salaam, Tanzania.
methodsA cross-sectional study was conducted from February to June 2024 at MNH Upanga and Mloganzila, enrolling 144 premature and LBW neonates via non-probability consecutive sampling. Serum creatinine levels were measured at admission, 48 h, and day seven or pre-discharge to diagnose AKI using KDIGO criteria. Data were analyzed with SPSS v26.0, employing chi-square tests for associations and robust Poisson regression for risk factor identification (p < 0.20 for univariable inclusion, p < 0.05 for significance).
resultsAmong 144 neonates (61.8% female, median age 5 days [IQR 3-12]), 65.3% received nephrotoxic drugs, primarily ampicillin-cloxacillin (58.3%) and gentamicin (54.9%). AKI was diagnosed in 26.4% of neonates, with 18.8% in stage 1, 6.3% in stage 2, and 1.4% in stage 3. Multivariable analysis identified male sex (aPR = 1.68, 95% CI: 1.01-2.89, p = 0.049) and exposure to two nephrotoxic drugs (aPR = 2.58, 95% CI: 1.20-5.55, p = 0.015) as independent risk factors for AKI.
conclusionAKI affects over a quarter of premature and LBW neonates in NICUs, with male sex and multiple nephrotoxic drug exposures as key risk factors. Implementing routine renal monitoring and optimizing pharmacotherapy are essential to reduce AKI incidence and improve neonatal outcomes in resource-constrained settings.
