Outcomes and readmissions after cardiac surgery in patients with chronic steroid use: a nationwide propensity score matched analysis.
Article in Journal of cardiothoracic surgery, 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
backgroundWe characterized index admission outcomes and 30-day readmissions after cardiac surgery in patients with chronic steroid use (CSU) in a large national administrative database.
methodsCardiac surgery patients (coronary artery bypass grafting, valve, aortic, and combinations) were identified in the 2016-2020 Nationwide Readmissions Database and stratified by CSU diagnosis. Mortality and complications during index admissions and 30-day readmissions were compared between patients with and without CSU after propensity score matching (PSM).
resultsOverall, 1,332,806 cardiac surgery patients were identified; 12,082 (0.91%) with CSU and 1,320,724 (99%) without. Before PSM, more CSU patients were ≥ 75 years-old and female, and had anemia, chronic lung disease, renal failure, and prior stroke. Following PSM, no significant differences in characteristics remained between 12,082 patients with CSU and 47,180 without. Index admission mortality (3.2% vs. 3.6%; P = .09) and overall complications (45% vs. 44%; P = .24) were not significantly different. 30-day readmissions were higher among those with CSU (16% vs. 13%; P < .01). Among readmitted patients, mortality (4.9% vs. 3.7%; P = .17) and overall complications (53% vs. 51%; P = .29) were not significantly different.
conclusionsPatients with CSU had higher baseline comorbidity burden but did not have higher index admission mortality or complications. Patients with CSU were more often readmitted within 30 days of discharge, but their outcomes during readmissions were like those in patients without CSU.
