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

backgroundLaparoendoscopic single-site surgery and natural orifice transluminal endoscopic surgery attempt to reduce transabdominal port sites. These require all instruments to pass through a single access point, leading to instruments collide or work at unfamiliar angles. Thus, we designed an internal grasper under magnetic anchoring guide system (MAGS) platform and investigated its utility and operability.

methodsWe measured the configuration for magnetic force decay over distance using a standardized, ex vivo laboratory testing apparatus. An electronic balance was used to measure the force of the gallbladder pull in ten patients with gallbladder stones. One pig (11 mm abdominal wall thickness) underwent a compressed trial of MAGS platform. The device was left in place for 20 min before tissue sections were harvested, and histologic assessment was performed. The utility and operability were investigated in four pigs (38-280 kg weight).

resultsThe magnetic attraction force decayed exponentially over distance; the force of pulling gallbladder was 7.46 ± 0.54 N. This pairing of components allowed for coupling to a theoretical distance of 10 mm. No gross tissue damage was observed. H-E stain showed no necrosis in all specimens. One failed due to wall thickness of 45 mm. Others showed the critical view, triangulation of instruments was obtained, and instrument collision or "sword fighting" was reduced.

conclusionsThe MAGS platform overcomes limitations such as collisions and lack of triangulation, reduces transabdominal port sites, and is easy to operate. However, our internal grasper requires the abdominal wall thickness below 10 mm.
