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

purposeAlthough minimally invasive cardiac surgery (MICS) procedures are widely performed throughout Japan, nationwide data regarding treated cases are limited. Up-to-date results for cardiovascular surgery are vital for quality control in clinical practice. Presented here is the 2021 annual report based on data from the Japan Cardiovascular Surgery Database (JCVSD).

methodsRecords noted in the JCVSD of patients who underwent mitral valve surgery, aortic valve replacement (AVR), coronary artery bypass grafting (CABG), atrial septum defect (ASD) closure, or cardiac tumor resection via right or left minithoracotomy, as well as thoracoscopic- or port-assisted, or robotic-assisted approaches, in 2021 were examined. Perioperative parameters including mortality and morbidity was evaluated.

resultsThe 30-day and in-hospital mortalities for isolated mitral valve repair (n = 1211) were 0.1% and 0.2%, respectively, while those for all mitral valve repair (n = 2017) were 0.05% and 0.2%, respectively. More than 100 facilities were found to perform fewer than five MICS mitral valve surgery cases per year. As for MICS-AVR, 30-day and in-hospital mortalities for isolated AVR (n = 818) were 0.5% and 0.5%, respectively, while those for all AVR (n = 987) were 0.6% and 1.1%, respectively. Additionally, those for MICS-CABG (n = 400) were 0.8% and 0.5%, respectively. Those for ASD (n = 183) and cardiac tumor (n = 96), were 0.5% and 0.5%, respectively, and 0% and 1.0%, respectively.

conclusionThis is the first report of MICS results of procedures performed in Japan based on the 2021 JCVSD data. Additional results obtained with a similar data collection method are expected and details on MICS are being collected starting 2024.
