Surgeons' Perception Questionnaire on Robotics (SPQR): development and preliminary validation of a surgeon-reported instrument for robotic surgery.
Article in Journal of robotic surgery, 2026. 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
Robotic surgical platforms are diversifying, and clinical outcomes are increasingly comparable across systems, yet the console surgeon's subjective experience remains poorly characterized. We developed a surgeon-reported questionnaire on robotic surgical systems and performed a preliminary psychometric evaluation in robotic radical prostatectomy. The Surgeons' Perception Questionnaire on Robotics (SPQR) includes 31 five-point items in six domains: technical and operational aspects, key surgical tasks, ergonomics and physical comfort, communication and workflow integration, learning curve, and overall evaluation. In a cross-sectional web-based survey, surgeons rated the platform they primarily used for robotic radical prostatectomy. Internal consistency was assessed with polychoric-based Cronbach's alpha and McDonald's omega; exploratory (EFA) and confirmatory factor analysis (CFA) were performed in the same sample. Fifty-nine surgeons participated (response rate 42%); 81% evaluated the da Vinci Xi. Overall internal consistency was high (alpha 0.96; omega 0.97). Alpha and omega were ≥ 0.84 in five domains but below 0.70 for ergonomics and physical comfort (0.64 and 0.67). EFA suggested three factors (system performance and satisfaction; learning curve and training; ergonomics). CFA showed high incremental fit (comparative fit index 0.985) but inadequate absolute fit (root mean square error of approximation 0.097; standardized root mean square residual 0.135), and the ergonomics factor was weakly defined. The SPQR showed high internal consistency in most domains and a provisional multidimensional structure. Because the sample was small, highly experienced, predominantly male, and dominated by one platform, these findings require confirmation in larger independent cohorts before the SPQR is used for platform comparisons.
