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

backgroundWeekend surgical time is an underused asset. Concerns over a possible weekend effect (substandard care) may be a barrier.

methodsThis study examined whether a weekend effect applies to elective colorectal surgery via a single-center retrospective analysis comparing outcomes between patients who underwent elective colorectal surgery on a weekend vs a weekday. Demographics, length of stay (LOS), operative and anesthesia time, the rate of reoperation within 30 days, and the rate of major complications were compared between patient groups.

resultsOf the 2008 patients identified, 1721 (85.7%) underwent surgery on a weekday, and 287 (14.3%) underwent surgery on a weekend. The proportion of operations with an open approach was higher on weekends than weekdays (49.5% vs 41.8%, P = .017). Patients who underwent surgery on the weekend tended to have a shorter mean (SE) for LOS (4.2 [0.2] vs 6.1 [0.2], P < .001), anesthesia time (233.8 [6.5] vs 307.6 [3.3] minutes, P < .001), and operative time (225.4 [6.4] vs. 297.6 [3.3] minutes, P < .001). On multivariable analysis, patients who had an operation on a weekend had a 38% lower chance of having a prolonged LOS (>75th percentile of LOS) compared with those who had an operation on a weekday (adjusted odds ratio = 0.62; 95% CI 0.42-0.92). There were no differences in rates of complications or reoperation for patients undergoing surgery on a weekend compared with a weekday.

conclusionAt centers with experienced anesthesiologists, appropriately trained nursing staff, and expert surgeons, colorectal surgery performed on a weekend has similar safety outcomes as surgeries performed on a weekday.
