An initial exploration of the daily associations between opioid use and acute suicide risk: The role of posttraumatic stress symptoms.
Article in Psychology of addictive behaviors : journal of the Society of Psychologists in Addictive Behaviors, 2026. 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
objectiveOpioid use and suicide frequently co-occur. Proximal posttraumatic stress symptoms (PTSS) may lead to co-occurring opioid use and acute suicide risk. Information from intensive longitudinal methods is needed to inform targeted intervention and policy for opioid use and suicide.
methodParticipants were 53 trauma-exposed adults recruited from the community who use opioids and were at elevated risk of suicide (
resultsPTSS were not associated with next-survey suicidal thoughts; instead, suicidal thoughts were significantly associated with next-survey PTSS (Standardized Fixed Effect Estimate = 0.53, 95% CI [0.25, 0.89]). Within-person opioid use-but not opioid cravings-significantly moderated the association between PTSS and next-survey suicidal thoughts (Standardized Fixed Effect Estimate = 0.40, 95% CI [0.02, 0.79]). Taken together, dynamic structural equation models and group iterative multiple model estimation findings indicated substantial heterogeneity in the momentary associations among PTSS, opioid cravings, and suicidal thoughts across individuals.
conclusionsThis study offers initial insight in the dynamic relations among PTSS, opioid use, and acute suicide risk. Importantly, findings call for future ecological momentary assessment work in this area to better inform clinical interventions for PTSS, opioid use, and suicide.
