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

backgroundMarijuana use is clinically problematic in depression, and non-medical and medical use may both contribute to barriers to care in this population. Among outpatients with depression, we examined the differential impact of medical or non-medical marijuana use, relative to no-use, on psychopathology and service use over time.

methodParticipants were 307 psychiatry outpatients participating in a trial of drug/alcohol use treatment for depression. Measures of past 30-day marijuana use, depression/anxiety symptoms, psychiatry visits, and functional data related to health status were collected at baseline, 3, 6, and 12 months. Regressions (baseline and 1 year) and growth models (over time) predicted clinical and psychiatry visit outcomes, from medical or non-medical marijuana use (no-use = reference).

resultsAt baseline, 40.0% of the sample used marijuana and more reported non-medical (71.7%) than medical (28.2%) use. Relative to non-users at baseline, patients using medically had worse mental/physical health functioning (p's < 0.05), and non-medical use was associated with higher suicidal ideation (B = 1.08, p = .002), worse mental health functioning (B = -3.79, p = .015), and fewer psychiatry visits (B = -0.69, p = .009). Patients using non-medically over time improved less in depression symptoms (B = 1.49, p = .026) and suicidal ideation (B = 1.08, p = .003) than non-users. LIMITATIONS: Participants were psychiatry outpatients, limiting generalizability.

conclusionsMarijuana use, especially non-medical use, among patients with depression may impede depression symptom improvement while lessening the likelihood of psychiatry visits. Marijuana use and associated barriers to care should receive consideration by depression treatment providers.
