Integrating Video and Objective Performance Data: Development of VORTEX-SPV for Assessing Robotic Lobectomy Skills.
Article in Innovations (Philadelphia, Pa.). 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
objectiveSurgical education requires assessment tools as part of competency-based education (CBE). In robotic surgery, objective performance indicators (OPIs) are a novel objective method of measuring surgeon performance. We developed
methodsCT fellows performed robotic lobectomy on an ex vivo perfused porcine model. Synchronized video and kinematic data were captured. Seven thoracic surgery attendings completed the robotic lobectomy to provide expert-level OPI data. VORTEX-SPV is a 12-item assessment with 4 performance levels including completion, safety, economy of motion, and optimized performance. We scored video-based review items (items 1 to 6) as 0 or 1 with an inter-rater agreement of 91%. We calculated OPIs from 6 categories (e.g., wrist articulation, instrument movement, energy, smoothness, clutching, instrument time) as within (1) or beyond (0) 2 standard deviations of the expert mean. We used Rasch modeling and item response theory to evaluate reliability and validity.
resultsWe assessed 2 cohorts of CT fellows (2019,
conclusionsVORTEX-SPV combines video review and objective performance data with strong reliability and validity evidence, serving as a robotic surgery assessment framework to facilitate CBE.
