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

backgroundHousing instability is common among people who inject drugs and is associated with poor health. We examined the association of homelessness with emergency department (ED) and inpatient (IP) utilization and charges among people who have injected drugs.

methodsParticipants were enrolled 2015-2024 in ALIVE, a cohort of Baltimore adults who have injected drugs. Past-six-month homelessness was reported at twice-annual study visits. ED and IP admissions and resulting charges to patients were ascertained through linkage to a state hospital billing registry. We estimated differences in rates of admissions and charges per-six-months comparing periods when participants did and did not experience homelessness, and adjusting for confounders such as substance use behaviors using balancing weights.

resultsAmong 1365 participants' 9896 study visits (66% male, 87% age 40-69), mean past-six-month rates of admissions and charges were 0.92 and $1408 respectively for the ED, and 0.19 and $4051 for IP. After confounding adjustment, ED admission rates (adjusted rate difference (aRD) = 1.37, 95% CI 0.79-2.42), IP admission rates (aRD 0.11, 95% CI 0.04-0.19), ED charges (aRD = $1720, 95% CI $1027 to $2726), and IP charges (aRD $2072, 95% CI $516 to $3760) were significantly higher during periods of homelessness. DISCUSSION: When people who injected drugs were experiencing homelessness, they experienced significantly elevated rates of ED and IP admissions and charges.
