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

backgroundLaparoscopic cholecystectomy (LC) seems to be more challenging in males than in females. The surgery seems to be longer in male patients. There also seems to be an increased rate of conversion to open surgery in male patients. We sought to objectively verify this widespread belief.

methodsWe performed a retrospective analysis of laparoscopic cholecystectomies performed between January 2004 and November 2009 in our hospital. Within this period 1844 cholecystectomies were performed in our community-based hospital. After a strict inclusion procedure, 1571 cases of LC for symptomatic gallbladder disease were analyzed (501 males, 1071 females). The time for surgery, defined as the interval from placement of the Veress needle to wound closure in minutes, and the rate of conversion to open surgery were the main parameters considered.

resultsThe time for surgery in male patients was significantly longer compared to that for females (p<0.0001). The male cohort was significantly older than the female cohort at the time of surgery (p<0.001). The rate of conversion to open surgery was significantly higher in male patients (5.6%) compared to 2.9% for females (p<0.0001).

conclusionBased on our analysis, LC had a significantly longer duration of surgery in the male cohort. The rate of conversion to open surgery was also significantly higher in male cohort. Thus, LC could be more challenging in male patients.
