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

To guide the prevention of policing in persons experiencing homelessness and mental illness, we examined police interactions in this population by combining data from At Home/Chez Soi and Montreal police databases (N= 454). We explored the types, initiators, locations, and mental health/judicial outcomes of interactions over four years, identifying sub-groups using latent class analysis and then comparing sociodemographic and psychosocial variables between groups. Four groups emerged: few, mainly as a suspect, diverse, and frequent and diverse interactions. The characteristics of participants with more suspect interactions are described. Grouping suggested the policing of behaviors associated with homelessness and underreporting of victimization.
