1 · What the graph read from it

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.

2 · The registry

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

This serial cross-sectional study assessed the nationwide prevalence and temporal trends of hospitalization for patients with unhoused status in the United States. The Agency for Healthcare Research and Quality’s Healthcare Cost and Utilization Project National Inpatient Sample was queried and included 241,001,774 hospital admissions for any indication from 2016 to 2022. Unhoused status, identified according to the National Health Care for the Homeless Council recommendation schema, was reported in 2,818,983 (1.2%) hospital admissions. Over the 7-year study period, the prevalence rate of hospitalizations for patients experiencing houselessness increased by 68.6% from 0.9% to 1.4% from 2016 to 2022 (average annual percentage change 8.7, 95% confidence interval 7.2 to 10.6). Hospital occupation rate by patients with unhoused status also increased from 1.4% to 2.1% (average annual percentage change 7.6, 95% confidence interval 4.6 to 11.2). Among the patients with unhoused status, the majority were male (71.7%) compared to female (28.3%). The majority of patients with unhoused status were White (54.9%), followed by Black (24.4%), and Hispanic (11.7%). The increasing rate of hospitalization with houselessness status was largest in Hispanic, followed by Native American, Black, Asian, and White. When assessed by U.S. census region, the Pacific division had a higher prevalence rate of hospital admissions for patients with unhoused status when compared to other divisions (2.2% versus 0.7%-1.5%, standardized mean difference 0.375). The annual increasing rate was highest in the East South Central division, followed by the West South Central and West North Central divisions (all, average annual percentage increase > 10%). In conclusion, this nationwide assessment suggests that the number of hospitalizations for people experiencing houselessness is increasing in the United States with variable differences across the geographic areas.
