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
introductionIncreasingly ambulatory surgery centers (ASC) are being used for patients undergoing total joint arthroplasty (TJA). The purpose of this study was to evaluate the effect of transitioning TJAs to a newly opened ASC on hospital quality measures of patients undergoing TJA in the hospital.
methodsA retrospective review of 7,775 patients undergoing TJA at a single hospital from January 2018 to October 2023 was performed. Overall, 4,554 cases who underwent TJA in the hospital from 2018 to 2019, before the ASC opening, were compared with 3,221 cases who underwent TJA in the hospital from 2022 to 2023, post ASC opening. Univariate statistics were used to examine differences between the groups.
resultsPost ASC opening, patients were older (69.8 vs. 66.8 years; P < 0.001) and a higher percentage of patients had an American Society of Anesthesiologists score of 3+ (50.6% vs. 41.7%; P < 0.001). Post ASC opening, more patients had 0-day length of stay (16.5% vs. 6.3%; P < 0.001), fewer were discharged to skilled nursing facility (6.9% vs. 9.3%; P = 0.002), and total charge was lower ($12,095.6 vs. $12,555.1 USD; P = 0.001).
conclusionFollowing the opening of an ASC, the acuity of TJAs performed in the hospital increased, but outcomes remained consistent or improved. The use of a coordinated clinical TJA pathway can potentially mitigate the adverse effects of increased hospital acuity after shifting appropriate patients to ASCs.
