Impact of delayed sternal closure and negative pressure therapy after complex cardiovascular surgery.
Observational study in Journal of cardiothoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo evaluate the safety of delayed sternal closure with negative pressure therapy in complex cardiovascular surgeries, with a focus on infectious complications, compared to primary sternal closure.
methodsThis retrospective observational study analyzed 285 adult patients undergoing complex cardiovascular surgeries between January 2019 and February 2021 at a quaternary care hospital. Patients were divided into delayed closure (N = 91) and primary closure (N = 194) groups. Propensity score matching was applied to adjust for baseline differences, resulting in 168 matched patients for outcome comparison.
resultsPatients from the delayed closure group more frequently required emergency surgery (37% vs. 4.6%, p < 0.001), experienced longer extracorporeal circulation times (median 140 min vs. 84 min, p < 0.001), and needed more intraoperative transfusions (98.9% vs. 68%, p < 0.001). Postoperative bleeding in the first 12 h was higher in the delayed closure group (median 500 ml vs. 250 ml, p < 0.001). Reoperation rates due to bleeding were higher in the delayed closure group in the unmatched cohort (19.8% vs. 8.8%, p = 0.014), but not in the matched cohort (p = 0.078). In-hospital mortality (13.2% vs. 7.2%, p = 0.2) and postoperative infection rates (3.6% vs. 3.3%, p > 0.9) were similar between groups. Patients who underwent delayed closure had longer ICU and hospital stays.
conclusionDelayed sternal closure with negative pressure therapy appears to be a safe management strategy for high-risk patients in complex cardiovascular surgeries. Despite increased transfusions and postoperative bleeding, delayed closure with negative pressure therapy did not result in higher mortality or infection rates compared to primary sternal closure.
