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

backgroundPsychiatric comorbidities are common in first-episode psychosis (FEP) and hinder recovery. Problem gambling (PBG), despite potentially serious clinical consequences, remains under-investigated in this population. This study aimed to estimate the incidence of PBG in FEP and identify predictive factors.

methodsThis prospective cohort study was conducted at two FEP programmes in Quebec, Canada. Individuals aged 18-35 years diagnosed with FEP between November-1-2019 and January-31-2023 were screened for PBG using the Problem Gambling Severity Index through May-1-2023. The primary outcome was incident PBG. Time-varying Cox regression models were used to estimate hazard ratios (HRs) for candidate predictors.

resultsAmong 520 individuals without prior PBG (mean age = 24.6±4.0 years; 28.8% women), 18 developed PBG during a mean follow-up of 478 days, yielding an incidence rate of 2.6 cases/ 100 person-years. In site-adjusted analyses, white ethnicity (HR = 9.7; 95%CI = 1.3-74.8), incomplete high school education (HR = 2.8; 95%CI = 1.1-7.2), stimulant use disorder (HR=2.8; 95%CI = 1.0-7.3), use of D2/D3-5-HT1A partial agonists (HR = 4.6; 95%CI = 1.5-14.1), and prior non-problematic gambling (HR = 3.1; 95%CI = 1.1-8.4) predicted increased risk. Thirteen cases occurred during aripiprazole treatment, which remained associated with increased PBG risk after multivariable adjustment (adjusted HR = 4.7; 95%CI = 1.6-13.9).

conclusionsDespite the limited number of incident cases, these results suggest that PBG is relatively common PBG and is associated with potential risk factors, including white ethnicity, incomplete high school education, stimulant use disorder, prior non-problematic gambling, and treatment with D2/D3-5-HT1A partial agonists, particularly aripiprazole. These findings underscore the importance of routine screening for PBG and risk-informed antipsychotic prescribing in FEP.
