Comparison of postoperative complications following CABG in diabetic and non-diabetic patients.
Article in ARYA atherosclerosis, 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
backgroundDiabetic patients face an elevated cardiovascular disease burden, often requiring coronary artery bypass grafting (CABG). However, evidence regarding post-CABG outcomes in diabetic versus non-diabetic patients is inconsistent, and data from the Iranian population are particularly scarce. This study was conducted to clarify this ambiguity by comparing short-term post-CABG complications between these groups.
methodsA retrospective cohort study analyzed data from the Yazd Cardiovascular Disease Registry (YCDR) for all CABG patients (2017-2018) at Afshar Hospital. Patients were stratified into diabetic (n=592) and non-diabetic (n=694) groups. We collected standardized data on demographics, comorbidities (including diabetes), and in-hospital major postoperative complications following CABG, such as reoperation, mortality, infections, renal complications, neurological complications (including TIA, stroke, and seizure), and pulmonary complications.
resultsThe frequency distribution of female sex (36.66% vs. 21.90%), hypertension (65.03% vs. 44.52%), and hyperlipidemia (39.02% vs. 23.20%) in diabetic patients was significantly higher than in non-diabetic patients (p<0.001). No statistically significant differences were observed between diabetic and non-diabetic groups in the incidence of major complications, including reoperation (2.1% vs. 2.3%), mortality (3.2% vs. 2.4%), and other major events (all p>0.05). However, seizure occurred exclusively in the diabetic group (1.1% vs. 0%; p=0.049). Logistic regression analysis demonstrated that diabetes mellitus was not an independent predictor of overall postoperative complications.
conclusionIn this cohort, diabetes was not an independent risk factor for most short-term post-CABG complications. The exception was a higher seizure incidence in diabetic patients, warranting further mechanistic investigation. Larger prospective studies are needed to confirm these findings.
