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

backgroundTwo-dimensional high-definition (2D HD) endovision system is preferred for laparoscopic surgery. Recently, new generation three-dimensional (3D) HD and ultra-HD (4K) endovision systems are introduced to improve the safety and efficacy of laparoscopic surgery. There is limited evidence on superiority of one technology over the others. This experimental trial was designed to evaluate 2D HD, 3D HD and 4K HD endovision systems in performance of standardized tasks.

methodsThis was a randomized, cross-over experimental study. Twenty-one surgical residents who were exposed to laparoscopic surgery were enrolled. Participants were randomly assigned into three groups. Each group performed standardised tasks i.e. peg transfer, precision cutting, navigating in space and intra-corporeal suturing using 2D HD, 4K HD and 3D HD endovision systems on a box trainer. Procedures were recorded as 2D HD videos and analysed later. Participant's perceived workload was assessed using Surg-TLX questionnaire. Primary endpoints were execution time in seconds and error score. Secondary endpoint was workload assessment.

resultsThe 3D HD had shorter execution time compared to 2D HD and 4K HD in all tasks except precision cutting (p = 0.004, 0.03, 0.001, 0.001 and p = 0.002, 0.191, 0.006, 0.005 in peg transfer, precision cutting, navigating in space and intra-corporeal suturing respectively). The 4K HD was significantly faster than 2D HD only in navigating in space task (p = 0.002). The error score between 3D HD and 4K HD were comparable in all tasks. The 2D HD had significantly more error scores compared to 4K HD, 3D HD in peg transfer task (p = 0.005, 0.014, respectively). 3D HD had significantly less workload than 2D HD and 4K HD in most of the dimensions of Surg-TLX

conclusions3D HD endovision system in comparison to 2D HD and 4K HD, may lead to faster execution without compromising safety of a task and is associated with less workload.
