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

objectiveTo assess how efficient the local team attained skills are after several visits made by international missions in respect to number of coronary artery bypass grafting surgery performed and the overall patient outcome.

methodsThis was a retrospective study that included all patients who were operated on at the center after being diagnosed with chronic coronary artery disease from May 2016 to December 2023. Patients' demographic data were retrieved from patients' files coupled with theatre record file, entered into a structured questionnaire, and then, in a statistical program.

resultsA total of 290 patients underwent coronary artery bypass grafting at the center. The international missions performed a total of 159 (54.8%) operations, while the local team operated a total of 131 (45.2%) patients. The study showed significant statistical difference in terms of total operation time (95% confidence interval [CI] = 5.67, 6.01 vs. 95% CI = 6.32, 6.66), aortic cross-clamping time (95% CI = 75.92, 90.00 vs. 95% CI = 111.19, 126.65), and total cardiopulmonary bypass time (95% CI = 115.9, 134.75 vs. 95% CI = 174.52, 201.27) between the international missions and local surgical team, respectively. The mortality rate was higher in patients operated on by the local team (13.7%) than by international missions (8.8%), however there was no statistical difference.

conclusionThis study has shown the beneficial advantage of international surgical missions to newly established open-heart centers with advanced facilities and skill-deprived team. International surgical missions have greatly contributed to the progression of the center as they oversee and support the programs.
