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

introductionThe 'weekend effect' describes variation in outcomes of patients treated over the weekend compared with those treated during weekdays. This study examines whether a weekend effect exists for patients who undergo emergency laparotomy. MATERIALS AND

methodsData entered into the National Emergency Laparotomy Audit between 2014 and 2017 at four NHS trusts in England and Wales were analysed. Patients were grouped into those admitted on weekdays and those on weekends (Friday 5pm to Monday 8am). Patient factors, markers of quality of care and patient outcomes were compared. Secondary analysis was performed according to the day of surgery.

resultsAfter exclusion of patients who underwent laparotomy more than one week after admission to hospital, a total of 1717 patients (1138 patients admitted on weekdays and 579 admitted on weekends) were analysed. Age, preoperative lactate and P-POSSUM scores were not significantly different between the two groups. Time from admission to consultant review, decision to operate, commencement of antibiotics and theatre were not significantly different. Grades of operating surgeon were also similar in both groups. Inpatient 60-day mortality was 12.5% on weekdays and 12.8% on weekends ( DISCUSSION: Quality of care and clinical outcomes for patients undergoing emergency laparotomy during the weekend are not significantly different to those carried out during weekdays.
