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

backgroundA number of studies have revealed higher postoperative mortality after operations that were performed toward the end of the week. It is not yet known whether a day-of-the-week effect exists after visceral surgical procedures for cancer in Germany.

methodsData on resections of carcinomas of the colon, rectum (2010-2017), and head of the pancreas (2014-2017) (n = 19 703) that had been prospectively acquired by the Study, Documentation, and Quality Center of the German Society for General and Visceral Surgery were analyzed in relation to the day of the week on which the operation was performed. The primary endpoint was postoperative 30-day mortality; the secondary endpoints were complications, length of hospital stay, and MTL30 (a combined outcome criterion that is positive if the patient has died, is still in the hospital, or has been transferred to another acute care hospital 30 days after the index procedure).

resultsResections of colon carcinomas that were performed on Mondays were associated with more advanced tumor stages (T4: 18.4% vs. 15.7%, p <0.001), higher 30-day mortality (3.5% vs. 2.3%, p = 0.004), and a more frequently positive MTL30 (10.5% vs. 8.5%, p = 0.004). Among patients who underwent pancreatic head resections, those whose procedures were on Tuesday had higher mortality (6.2% vs. 3.8%; p = 0.021). Among those who underwent surgery for rectal carcinoma, the day of the week on which the procedure was performed had no effect on postoperative morality. Multivariate analysis revealed that the independent risk factors for postoperative mortality were colonic resection on a Monday (odds ratio [OR]: 1.45; 95% confidence interval [1.11; 1.92], p = 0.008) and pancreatic head resection on a Tuesday (OR: 1.88 [1.18; 2.91], p = 0.006).

conclusionElective surgery for carcinoma of the colon or pancreatic head is associated with slightly higher mortality if per - formed toward the beginning of the week. On the other hand, the day of the week has no effect on the outcome of surgery for rectal carcinoma.
