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

objectivesA weekend effect with increased mortality has previously been reported in surgical patients and those with acute myocardial infarction (MI). We hypothesized that a similar phenomenon may exist in coronary artery bypass grafting (CABG).

methodsPatients undergoing non-elective isolated CABG (2011-2017) were included from a multicentre regional Society of Thoracic Surgeons database. Patients were stratified by weekend versus weekday operations and further analysed by specific day of the week.

resultsA total of 14 374 patients underwent urgent or emergency isolated CABG with 410 (2.9%) operated on over the weekend. Weekend operations were more often emergency (36.1% vs 5.0%, P < 0.001) and more likely to be in the setting of MI (70.0% vs 51.2%, P < 0.001). Cardiopulmonary bypass times were similar [91 min (71-114) vs 94 min (74-117), P = 0.0749] and the frequency of complete revascularization equivalent (83.4% vs 85.3%, P = 0.284) between weekend and weekday operations. In risk-adjusted analyses, there was no increased odds for mortality in patients operated on over the weekend [odds ratio (OR) 1.07, P = 0.811]; however, there was an increased odds of major morbidity (OR 1.37, P = 0.034). Furthermore, compared with Monday, morbidity increased as the operative day approached the weekend (Tuesday 0.98, P = 0.828; Wednesday 1.07, P = 0.469; Thursday 1.12, P = 0.229; Friday 1.19, P = 0.041; weekend 1.47, P = 0.014).

conclusionsWhile patients requiring surgery on the weekend are higher risk, there is no independent effect of weekend surgery on mortality. However, these patients are at increased risk for major morbidity, the causes of which require further investigation.
