Living alone predicts non-home discharge post elective hip arthroplasty: A matched-pair cohort study.
Article in PloS one, 2025. 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
The impact of home support and interaction with family members on recovery and perioperative outcomes remains unclear. We determined whether living alone was predictive of discharge disposition following total hip arthroplasty (THA). Data were from American College of Surgeons National Surgical Quality Improvement Program participating hospitals in 2021. The primary endpoint was discharging disposition. A total of 1716 patients living alone and 3961 with others at home were identified. The 1:1 propensity-matched cohort included 3248 total patients (1624 in each group). On univariate analysis, living alone was associated with non-home discharge (22.0% [358/1624] vs. 10.5% [170/1623]; odds ratio [OR], 2.42 [95% CI, 1.98 to 2.94]; P < .001), need for services in those returning home (63.1% [799/1266] vs. 57.7% [839/1453]; OR, 1.25 [95% CI, 1.07 to 1.46]; P = .004), and increased length of hospital stay (2.05 vs. 1.72 days; mean difference, 0.34 [95% CI, 0.18 to 0.49]; P < .001). On multivariable analysis, living alone remained an independent predictor of non-home discharge (adjusted odds ratio, 2.84 [95% CI, 2.30 to 3.54]; c = 0.734). Thus, compared to propensity-matched THA patients with others at home, those living alone experience a much greater rate of non-home discharge and need for support.
