Progression of serum creatinine and glomerular filtration rate in neonatal critical care patients during the first seven days of life.

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
backgroundSerum creatinine and estimated glomerular filtration rate (GFR) are key indicators of kidney function.
methodsThis descriptive, retrospective study included neonatal patients admitted to a tertiary hospital's neonatal intensive care unit from January 2013 to December 2016. Data on kidney function were collected from birth to 7 days of life. Patients were stratified into four gestational age groups: below 28 weeks, 28-31 weeks, 32-36 weeks, and term neonates. Qualitative variables were expressed as percentages. Quantitative variables were assessed using the Kruskal-Wallis/Wilcoxon tests. Chi-square analysis was performed for categorical variables. Statistical analysis was conducted using SPSS (Version 22.0), with significance set at p < 0.05.
resultsAmong 138 patients, 99 (71.7%) were premature. Term neonates showed a gradual postnatal decline in creatinine, while premature infants exhibited an initial rise followed by a decline, with values inversely proportional to gestational age (at seven days: 0.70 ± 0.19 mg/dL in below 28 weeks vs. 0.39 ± 0.08 mg/dL in term, p < 0.001). Among the clinical-epidemiological variables of the included patients, seven significantly influenced serum creatinine. GFR decreased in premature neonates at 24 h, then increased throughout the study. Term neonates demonstrated a progressive GFR increase, with higher values associated with greater gestational age (at seven days:16.8 ± 5.0 ml/min/1.73m
conclusionsEvaluating kidney function in neonates, based on serum creatinine and GFR, requires special attention during the first days of life, particularly in critically ill neonates due to multiple physiological changes and clinical factors that may influence these parameters.
