Sternal Closure Techniques Using Steel Wires and Predictors of Sternal Wound Complications: A Randomized Controlled Trial.
Trial report in Brazilian journal of cardiovascular surgery, 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
introductionMedian sternotomy is the gold standard for cardiac surgery but carries a significant risk of wound complications, including sternal dehiscence and wound infections.
objectiveThis study aimed to compare the early efficacy and complication rates of three distinct steel-wire sternal closure techniques and identify potential risk factors of complications.
methodsWe conducted a randomized controlled study on patients undergoing cardiac surgery. Patients were randomly allocated into three groups of sternal closure techniques: simple interrupted (Group A), figure-of-eight (Group B), or a modified combined technique (Group C). Baseline characteristics, intraoperative parameters, postoperative recovery outcomes, and sternal wound complications including sternal dehiscence and superficial and deep wound infections were evaluated. Binomial logistic regression was performed to determine independent risk factors for complications.
resultsOne hundred sixty-five adult cardiac patients were finally included in the study. All three intervention groups (n = 55) were well-matched regarding baseline characteristics and intraoperative parameters. The incidence of sternal dehiscence (6.1%) and superficial (7.9%) and deep wound infections (3.6%) did not differ significantly among the three wire closure techniques (P > 0.05). However, logistic regression identified numerous factors associated with superficial sternal wound infections including old age, obesity (body mass index > 30), comorbidities, elevated C-reactive protein and HbA1C, prolonged cardiopulmonary bypass time, extended operative time, and longer intensive care unit stay (P < 0.05 for all).
conclusionThe three steel-wire closure techniques demonstrated comparable early postoperative stability and similar rates of sternal wound complications. Technique choice may be based on surgeon preference.
