Correction: Application of the comprehensive complication index and Clavien-Dindo complication classification in cardiac surgery: a retrospective study.
Article in BMC cardiovascular disorders, 2025. 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
backgroundStandardized tools are needed to accurately assess the severity of postoperative complications in cardiac surgery, which is critical for patient management and outcome evaluation. This study aims to evaluate the application of the Clavien Dindo Complications Classification (CDCC) and Comprehensive Complications Index (CCI) in cardiac surgery.
methodsA single-center retrospective analysis was conducted on 738 patients who underwent cardiac surgery between January 2021 and December 2023. The CDCC and CCI were used to evaluate postoperative complications. The age-adjusted Charlson comorbidity index (ACCI) and LVEF were also evaluated. Multivariate regression models according to the most severe complications (CDCC ≥ IIIb grade) were tested. We compared the CDCC and CCI with the patient's surgical condition and economic burden and calculated the sample size required for different evaluation types.
results563 patients (76.3%) had at least one complication. The mean CCI was 22.5 ± 19.3. Patients who underwent more complex surgeries had higher CDCC grades and CCI scores. Hospitalization cost and length of stay increased with increasing CDCC grade and CCI score. The ACCI (OR: 1.334 [1.109-1.606], p = 0.002) and LVEF (OR: 0.965 [0.943- 0.987], p = 0.002) were associated factors for the most severe complications. The CCI may reduce the required sample size by 20.5 times and 19.6 times compared with the most severe complication or major adverse cardiovascular and cerebrovascular events, respectively, as an endpoint.
conclusionThe CCI and CDCC can help reflect the complexity of cardiac surgery and the burden of hospitalization, providing a more accurate assessment of surgical complications. This may reduce the sample size needed for clinical trials, thus facilitating research in cardiac surgery. CLINICAL
