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

objectivesIn Japan, off-pump coronary artery bypass (OPCAB) is more common than on-pump coronary artery bypass. Superior early results of OPCAB have been reported; however, long-term results were still unclear. Purpose of this study is to evaluate the clinical outcomes of OPCAB in Japan using Japan Adult Cardiovascular Surgery Database.

methodsBetween 2008 and 2010, 23,633 patients who underwent isolated coronary artery bypass were reported in database. We selected the cases from the hospital with mean annual coronary surgery volume of more than 50. Among the total of 7724 cases at 41 institutions, 2150 (31.2%) on-pump coronary artery bypass (ONCAB) and 5574 (68.8%) OPCAB cases were included. Propensity score (PS) matching was performed using PS developed from patient characteristics and preoperative factors resulting in 2007 cases matched pairs. Long-term follow-up data on patients' mortality and stroke were collected.

resultsIn-hospital mortality was significantly lower in OPCAB (ONCAB 1.1%, OPCAB 0.4% p = 0.01). Stroke was low in OPCAB group (ONCAB 1.7%, OPCAB 0.8%, p = 0.01). There was no statistically significant difference between OPCAB and ONCAB regarding 7-year overall survival (86.1% vs 88.1% respectively), composite outcomes (72.0% vs 73.9% respectively), or cardiac deaths (97.3% vs 97.1% respectively). Subgroup analysis (more than 75 years old) showed a worse trend in OPCAB group. Only in OPCAB group, incomplete revascularization significantly influenced 7-year survival.

conclusionsOPCAB is associated with early prognostic benefits; however, it might be less favorable outcomes in the long term when patients are older or with incomplete revascularization.
