Video-Rated Performance Assessment of Simulated Laparoscopic Sleeve Gastrectomy: Validation of a Sleeve Gastrectomy Rating Scale.
Observational study in Obesity surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
purposeThe global rise in obesity has been accompanied by widespread uptake of the procedure of laparoscopic sleeve gastrectomy. Despite this, the key components for performance assessment have not been standardized for this procedure. The aim of this study was to develop and demonstrate the validity of a Sleeve Objective Structured Assessment of Technical Skill (SOSATS) scale for learning the procedure of laparoscopic sleeve gastrectomy (LSG). MATERIALS AND
methodsThe SOSATS evaluation tool was based upon critical steps of the LSG procedure. Both the SOSATS and the Global Rating Scale (GRS) component of the Objective Structured Assessment of Technical Skill (OSATS) tools were utilized in a prospective single-blinded observational study design of 26 video recordings of surgeons performing sleeve gastrectomies using a novel simulation. The surgeons were allocated into "novice" or "experienced" groups dependent on case-volume criteria. Surgical performance was assessed using both the GRS and SOSATS scales by blinded assessors of the video recordings.
resultsFace and content validity were demonstrated for key components of the simulated model. An overall positive correlation was established inferring concurrent validity between the accepted OSATS Global Rating Scale against the SOSATS procedural scale. Construct validity was established for a number of areas of the SOSATS scale.
conclusionThe SOSATS scale is shown to exhibit construct and concurrent validity in the simulated setting for the procedure of sleeve gastrectomy. Utilizing this scale to review surgical performance is potentially feasible and reliable but would require further research prior to use in high-stakes assessment processes such as credentialing.
