Perioperative risk factors for mortality in mediastinitis following cardiac surgery.
Article in BMC cardiovascular disorders, 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
objectiveMediastinitis is a rare but highly morbid and mortal complication of cardiac surgery. This study aims to examine the potential perioperative risk factors associated with mortality among patients who developed mediastinitis following cardiac surgery with median sternotomy.
methodsThis retrospective study included 81 adult patients who developed mediastinitis following cardiac surgery with median sternotomy. Data on demographics, clinical/laboratory results, and mortality were extracted. Factors associated with mortality were examined. Comparative analyses were performed using appropriate parametric or non-parametric tests, depending on data distribution. Categorical variables were compared using the chi-square or Fisher’s exact test. Receiver operating characteristic analysis was used to assess predictive performance.
resultsAmong the 81 mediastinitis patients included for analyses, 36 died and 45 survived. Based on multivariate analysis, use of blood or blood products (OR: 33.99; 95% CI: 1.84–626.78, p = 0.018) and increased serum procalcitonin levels reflecting disease severity during mediastinitis (OR: 1.62; 95% CI: 1.02–2.57, p = 0.039) were associated with higher mortality risk; on the other hand, higher serum albumin levels during the course of mediastinitis were associated with a lower risk of mortality (OR: 0.04; 95% CI: 0.00–0.28, p = 0.011). In further analysis, mortality was found to be higher in patients with serum albumin levels below 2.21 g/dl, with a sensitivity of 86.1% and specificity of 86.7%.
conclusionsLow serum albumin levels, blood and blood product use, and elevated procalcitonin levels were associated with increased mortality in poststernotomy mediastinitis, with serum albumin being the strongest prognostic marker.
