1 · What the graph read from it

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.

2 · The registry

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

Objectives: This retrospective cohort study aimed to investigate the incidence, predictors, and outcomes of surgical re-exploration for postoperative bleeding in patients undergoing elective, isolated off-pump coronary artery bypass grafting (OPCAB). Methods: Patients undergoing elective isolated OPCAB were included in the study. Patients were categorized into two groups: those requiring re-exploration for postoperative bleeding and those not requiring re-exploration. Demographic, clinical, and operative variables were compared. Multivariable logistic regression was used to identify independent risk factors for re-exploration and 30-day mortality. Results: Out of the 4,957 eligible patients, 178 (3.6%) required surgical re-exploration for postoperative bleeding. Patients undergoing re-exploration were significantly older (61.4 ± 7.25 years vs. 58.75 ± 8.97 years, Conclusions: Re-exploration is not just a surgical technical event, but a critical turning point that dramatically alters patient outcome. It is, therefore, paramount to identify high-risk patients and develop strategies to reduce bleeding complications and re-explorations in order to improve patient outcomes.
