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

backgroundPoor engagement with Early Intervention Services (EIS) for first-episode psychosis threatens program effectiveness, yet research often reduces engagement to a binary measure (engaged/disengaged), limiting understanding of those who disengage and re-engage. This study examined demographics, clinical characteristics, and health service utilisation patterns among engaged, intermittently engaged, and disengaged patients of the Nova Scotia Early Psychosis Program (NSEPP).

methodsA retrospective cohort comprised of 331 individuals enrolled in NSEPP between July 22, 2005, and October 9, 2015, was constructed by linking clinical and administrative datasets. Engagement types (engaged, intermittently engaged, disengaged) were characterised in terms of baseline demographics and clinical factors, along with patterns of health service utilisation before, during, and after program enrollment. Crude and adjusted associations between program engagement and post-program health service utilisation (emergency department (ED) use and mental health-related hospital admissions) were assessed using negative binomial regression models.

resultsDuring program enrollment, the intermittently engaged group had the greatest illness severity (35% spent 30+ days in hospital), and the highest proportion of individuals with at least one ED visit (85%) and one hospital admission (55%). These during-program health service use factors were the strongest predictors of post-program health service use outcomes.

conclusionsThe three engagement types show distinct health service utilisation patterns, which may reflect differences in need, access, or program effectiveness. These results provide evidence that dichotomisation of engagement may mask important heterogeneity. Further characterisation of the engagement continuum to include intermittent engagement may provide insights to reducing barriers and improving access to and uptake of EIS.
