Limited effect of leg elevation in preventing intraoperative hypotension during total shoulder arthroplasty in the beach chair position: a randomized controlled trial.
Trial report in BMC anesthesiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03393559 (The Effect of Leg Elevation on the Prevention of Intraoperative Hypotension During Shoulder Surgery in the Beach Chair Position), which is not on this map.

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.

Abstract
backgroundThe beach chair position, often used in shoulder surgery, increases the risk of hypotension and cerebral hypoperfusion. This randomized controlled trial evaluated the efficacy of leg elevation in preventing hypotension during total shoulder arthroplasty in the beach chair position.
methodsFifty patients scheduled for total shoulder arthroplasty in the beach chair position were randomly assigned to the control (25 patients) or treatment (25 patients) groups. The treatment group elevated their legs during surgery, whereas the control group maintained a neutral leg position. The primary outcome was the incidence of hypotension. The secondary outcomes included the incidence of cerebral desaturation, hemodynamic variables, and vasoconstrictor use.
resultsThe incidence of hypotension did not significantly differ between the control and treatment groups (100% [95% CI: 86.3-100%] vs. 87.5% [95% CI: 67.6-97.3%]; p = 0.11). The incidence of cerebral desaturation was also similar between the control and treatment groups (84.0% [95% CI: 63.9-95.5%] vs. 91.7% [95% CI: 73.0-99.0%]; p = 0.67). However, the median [Q1-Q3] dose of phenylephrine was significantly higher in the control group than in the treatment group (3.5 [1.5-5.4] μg/kg vs. 1.6 [0.9-3.0] μg/kg; p = 0.02).
conclusionsIntraoperative hypotension occurred in 93.9% of patients undergoing total shoulder arthroplasty in the beach chair position, regardless of leg elevation. However, leg elevation significantly reduced the need for vasoconstrictors to maintain blood pressure during anesthesia.
