Perceived vs. true glenoid anchor placement: a cadaveric comparison of the beach chair and lateral position.
Article in JSES international, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo explore whether patient position influences a surgeon's ability to accurately judge anchor position on the glenoid. MATERIALS AND
methodsTwo anchors were inserted into the glenoid of 8 shoulders. Arthroscopic videos were taken from 3 views (posterior beach chair [pBC], posterior lateral decubitus [pLD], and anterosuperolateral decubitus [asLD]). The shoulders were disarticulated to identify "true" anchor position. Seventeen shoulder surgeons reviewed the videos and indicated anchor positions using the "clock face" method. Accuracy was measured within tolerances, ranging from zero (exact), 0.5 (half-hour), 1.0, and 1.5 hours of "true" position. Intra- and inter-rater agreement was calculated. Post hoc analyses explored for bias dependent on surgical side.
resultsThe overall accuracy was 34.0%. At tolerances of 0.5, 1.0, and 1.5 hours, accuracy increased to 82.4%, 95.4%, and 98.0%. With a 30° scope, identification of exact position was more accurate in pBC than pLD (odds ratio [OR] = 1.397;
conclusionJudgment of anchor position on video is most accurate in a pBC view. Inter- and intrarater reliability were also highest from a pBC view.
