Substance use and posttraumatic stress disorder: 12-month outcomes among adults experiencing chronic homelessness in Australia.
Trial report in Drug and alcohol review, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionSubstance use disorder and posttraumatic stress disorder (PTSD) are highly prevalent among individuals who experience homelessness. However, evaluations of interventions that combine housing and mental health services have reported inconsistent mental health and substance use outcomes when compared to usual services. We investigated 12-month change in substance use severity and PTSD symptom severity among adults experiencing chronic homelessness and tested whether observed differences were associated with housing, support from mental health services or the Journey to Social Inclusion (J2SI) program.
methodsA randomised controlled trial compared the J2SI program with standard service provision (N = 135). Secondary analyses compared those who obtained housing or received mental health services with those who did not. Primary outcomes were alcohol and illicit substance use severity (alcohol, smoking and substance involvement screening test) and PTSD symptom severity (six-item PTSD checklist).
resultsThere was significant improvement at 12 months in alcohol use severity, illicit substance use severity and PTSD symptoms in the overall sample. Having seen a mental health professional in the previous 12 months was associated with a significant reduction in alcohol and illicit substance use severity but was not associated with changes in PTSD symptom severity. Being housed at 12 months was associated with significantly higher alcohol use severity. DISCUSSION AND
conclusionsFindings highlight the importance of access to mental health care for people with a history of chronic homelessness. Research is needed to develop and test therapeutic and housing approaches to reduce PTSD symptom severity among people with experience of homelessness.
