Sustained hypotension during shoulder arthroscopy is associated with postoperative nausea and vomiting.
Article in PloS one, 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
backgroundPostoperative nausea and vomiting (PONV) is a common and distressing complication following shoulder arthroscopy. Although hypotension is known to trigger nausea, the specific association between sustained intraoperative hypotension (SIH) during shoulder arthroscopic surgery and PONV has not been well characterized. This retrospective study aimed to investigate whether SIH is independently associated with PONV.
methodsWe retrospectively analyzed data from 306 patients who underwent shoulder arthroscopy between March 2018 and January 2024. SIH was defined as a ≥ 20% decrease in mean arterial pressure (MAP) from baseline persisting for at least 60 minutes during the controlled hypotension phase. Univariate logistic regression analysis and multivariate exact logistic regression analysis were performed to identify factors associated with the occurrence of PONV. PONV severity was compared between the SIH and non-SIH groups using the chi-square test.
resultsPONV occurred in 96 patients (31.37%). Univariate logistic regression analysis revealed that females, smoking, history of motion sickness and/or PONV, and SIH were related to the occurrence of PONV (all p < 0.05). Multivariate logistic regression analysis revealed that females (adjusted OR: 3.966, 95% CI: 2.149-7.317, p < 0.001), smoking (adjusted OR: 0.232, 95% CI: 0.107-0.501, p < 0.001), history of motion sickness and/or PONV (adjusted OR: 32.393, 95% CI: 3.801-276.051, p = 0.001), and SIH (adjusted OR: 2.198, 95% CI: 1.289-3.749, p = 0.004) were independently associated with the occurrence of PONV. Additionally, patients with SIH exhibited significantly higher severity grades for both nausea (p = 0.002) and vomiting (p = 0.007).
conclusionSIH due to controlled hypotension during shoulder arthroscopic surgery was independently associated with PONV. SIH may serve as a clinically relevant predictor for PONV.
