Hand Surgeons Performing More Open Carpal Tunnel Releases Do Not Show Better Patient Outcomes.
Article in Plastic and reconstructive surgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
backgroundAlthough previous studies have shown that more experienced surgeons have better patient outcomes following a variety of procedures, in hand surgery and carpal tunnel release in particular, this relation remains unproven. The authors assessed whether there is an association between surgeon volume and patient outcomes following open carpal tunnel release.
methodsPatients who underwent carpal tunnel release between 2011 and 2015 at outpatient hand surgery clinics in The Netherlands were included. Surgeon annual volume was defined as the average number of carpal tunnel releases performed per year per participating surgeon over the study period. Primary outcome measures were the Symptom Severity Scale and Functional Status Scale of the Boston Carpal Tunnel Questionnaire 6 months postoperatively. Multilevel random intercept linear regression analyses were performed to assess whether there was an association between surgeon annual volume and outcome measures, with adjustment for patient characteristics, concomitant procedures, and intake score on the Boston Carpal Tunnel Questionnaire.
resultsA total of 1345 patients were included, operated on by 17 surgeons. Median annual surgeon volume was 75 (interquartile range, 50 to 149). Only 0.5 to 0.6 percent of the total variance in patient outcome on the Boston Carpal Tunnel Questionnaire could be explained by random differences between surgeons. The authors did not find an association between annual surgeon volume and outcome measures 6 months postoperatively (Symptom Severity Scale: β = 0.000; 95 percent CI, -0.001 to 0.001; and Functional Status Scale: β = 0.000; 95 percent CI, -0.001 to 0.001).
conclusionIn the authors' sample of highly specialized hand surgeons operating in high-volume centers, they found no differences in outcome between high- and low-volume surgeons.
