Characterizing clinical heterogeneity in an inpatient service treating mental, substance use and concurrent disorders.
Article in PLOS mental health, 2024. 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
Patients diagnosed with concurrent disorders (CD)-comorbid substance use disorder with other psychiatric conditions-experience poorer clinical outcomes, and significant gaps remain in defining the optimal care path for treating CD. Toward this goal, the primary aim of this study was to characterize individual differences in substance use and psychiatric symptomology in an inpatient clinical sample using a person-centred approach. Admission assessment data from a private inpatient service treating mental disorders, substance use, and concurrent disorders was used (n = 177). Latent profile analysis (LPA) was performed to classify individuals into statistically distinct latent profiles based on their psychiatric symptoms and polysubstance use as covariates. LPA revealed four profiles. Profile 1 (20%) was identified as having low SUD and low psychiatric disorders, profile 2 (65%) was identified as having low SUD and high psychiatric disorders, profile 3 (8%) was characterized as high substance use and moderate psychiatric disorders and profile 4 (7%) was identified as the high SUD and high psychiatric disorders. The participants in the two profiles endorsing high SUDs, Profiles 3 and 4, showed significantly higher impulsivity in terms of higher positive urgency sensation-seeking scores compared to the other profiles and the highest use of cocaine/stimulants than the other two. Identifying clinical heterogeneity by classifying individuals into distinct profiles is a first step toward designing more targeted and personalized interventions in clinically complex inpatient populations.
