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

backgroundBariatric surgery was established at several Norwegian hospitals in 2004. This study evaluates the perioperative outcome and the learning curves for two surgeons while introducing laparoscopic Roux-en-Y gastric bypass (LRYGB).

methodsMorbidly obese patients undergoing primary LRYGB were included. Lengths of surgery and postoperative hospital stay, and 30-day rates of morbidity, reoperations, and readmissions were set as indicators of the learning curve. Learning effects were evaluated by graphical analyses and comparing the first and last 40 procedures for both surgeons.

resultsThe 292 included patients had a mean age of 40.0 +/- 9.5 years and a mean body mass index (BMI) of 46.7 +/- 5.3 kg/m(2). The mean length of surgery was 101 +/- 55 min. Complications occurred in 43 patients (14.7%), with no conversions to open surgery in the primary procedure and no mortality. Reoperations were performed in 14 patients (4.8%), of which five patients required open surgery. The median length of stay was 3 days (range 1-77), and 19 patients (6.5%) were readmitted. High patient age, but not high BMI, was associated with an increased risk of complication. For both surgeons, lengths of surgery and hospital stay were significantly reduced (p < 0.001), leveling out after 100 procedures. Reductions in the rates of morbidity, reoperations and readmissions were not found.

conclusionLRYGB was introduced with an acceptable morbidity rate and no mortality. Only the length of surgery and postoperative hospital stay were suitable indicators of a learning curve, which comprised about 100 cases.
