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

introductionDuring laparoscopy, the monitor is usually placed near the operating table, at eye level, which significantly affects hand-eye coordination. First, it is impossible for the surgeon to simultaneously observe the operative field and hand movement. Second, the axis of view of the endoscope rarely matches the natural axis of the surgeon's sight: it resembles a direct view into the operative field. Finally, as the arms of the tools act as levers with a fulcrum at the site of the skin incision, the action of the tool handles is a mirror image of the movement of the tool tips seen on the monitor. Studies have shown that a neutral position with the head flexed at 15-45° is the most ergonomically suitable.

aimTo evaluate whether the level of monitor placement exerts an influence on laparoscopic performance. MATERIAL AND

methodsA group of 52 students of medicine were asked to pass a thread through 9 holes of different sizes, placed at different levels and angles, using a self-made laparoscopic simulator. Each student performed the task four times in two monitor positions: at eye level, and placed on a simulator. The order of monitor placement was randomized.

resultsThe task was performed more quickly when the monitor was placed on the simulator and the sight was forced downwards. Lower placement was also found to be more beneficial for students with experience in laparoscopy.

conclusionsNew technologies which place the display on the patient, thus improving the ergonomics of the operation, should be developed.
