Operative duration-based learning period analysis for reverse and total shoulder arthroplasty: A multicenter study.
Article in Shoulder & elbow, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundA surgical learning period may be quantified after which operative duration is significantly reduced. We sought to retrospectively quantify and compare surgeon's learning experience for total shoulder arthroplasty and reverse shoulder arthroplasty.
methodsWe reviewed 2055 shoulder arthroplasty cases from 2011 to 2015 for four early-career and four later-career fellowship-trained shoulder surgeons from four institutions. We plotted consecutive case number versus operative time for each surgeon separately for total shoulder arthroplasty or reverse shoulder arthroplasty. Two-step regression approach was used to determine a plateau point or end of the learning period. Additionally, the mean annual volume of reverse shoulder arthroplasty and total shoulder arthroplasty for each surgeon was plotted against mean surgery duration. Early- and later-career surgeons were compared with regression analysis.
resultsEarly-career surgeons demonstrated a significant decrease in operative time with increasing annual case volume for reverse shoulder arthroplasty (
conclusionFor only early-career surgeons, higher case volume yields decreased operative duration, with improvement more pronounced for reverse shoulder arthroplasty compared to total shoulder arthroplasty. Though the learning period varies, it may be fewer than 90 cases.
