Determinants of the renal function after the coronary artery bypass grafting in chronic kidney disease patients: a prospective cohort study.
Article in Journal of cardiothoracic surgery, 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
backgroundThis study aims to evaluate renal outcomes and identify key factors influencing estimated glomerular filtration rate (eGFR) in patients with chronic kidney disease(CKD) undergoing coronary artery bypass grafting (CABG).
methodsIn a prospective cohort of 100 patients with CKD (mean age 65.5 years; 77% male; most in CKD stage 2 or 3), eGFR was measured at baseline, three months, and six months postoperatively. Generalized Estimating Equations (GEE) were applied to assess longitudinal changes in eGFR and associated predictors. Statistical analyses were performed using Stata 17.
resultsApproximately 19% of patients experienced a > 30% decline in eGFR, while over 40% demonstrated improvement at six months. Advanced CKD stage, higher preoperative heart ejection fraction (EF), and longer anesthesia time were associated with greater eGFR decline. Conversely, higher preoperative hemoglobin (Hb) levels, elective surgery, and a history of cerebrovascular accident were associated with improved estimated eGFR trends.
conclusionSeveral clinical and procedural factors influence postoperative renal function in CKD patients undergoing CABG. These findings support the development of targeted perioperative strategies to mitigate renal decline. CLINICAL
trial registrationThis study does not meet the criteria of a clinical trial and, therefore, was not registered in a clinical trial registry.
