Early Postoperative Complications and Risk Assessment in Cardiac Surgery: A Cohort Study.
Article in Annals of cardiac anaesthesia, 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
backgroundEarly postoperative complications are major determinants of outcomes after cardiac surgery, particularly in low- and middle-income countries (LMICs), where perioperative data remain limited.
aimTo describe the incidence and spectrum of early postoperative complications within the first 24 hours after cardiac surgery and to characterize preoperative risk profiles using cardiac anesthesia risk evaluation (CARE) and European system for cardiac operative risk evaluation (EuroSCORE) II. SETTINGS AND
designRetrospective, single-center cohort study conducted at a national referral hospital. MATERIALS AND
methodsA total of 108 adult patients undergoing cardiac surgery with cardiopulmonary bypass between 2017 and 2021 were included. Baseline clinical and surgical variables were collected. Early postoperative complications were recorded by organ system. CARE and EuroSCORE II were calculated preoperatively due to absence of mortality data. STATISTICAL ANALYSIS USED: Descriptive analysis was performed. The discriminative ability of CARE-predicted morbidity was evaluated using the area under the receiver operating characteristic curve (AUC) with 95% confidence intervals.
resultsThe mean age was 50.1 ± 17.1 years, and 52.8% were women. Early postoperative complications occurred in 47 patients (43.5%), most frequently cardiovascular (42 patients, 38.9%), followed by renal complications requiring renal replacement therapy (11, 10.2%), infectious (9, 8.3%), and respiratory complications (8, 7.4%). CARE-predicted morbidity showed limited to moderate discrimination (AUC 0.67; 95% CI 0.58-0.77). EuroSCORE II was reported descriptively.
conclusionEarly postoperative morbidity is common in this LMIC cohort, with cardiovascular complications predominating. CARE-predicted morbidity showed limited to moderate discrimination, supporting cautious interpretation and highlighting the need for improved perioperative outcome monitoring.
