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
backgroundIt is not known if there are differences in antipsychotic initiation between migrants and native-born individuals diagnosed with non-affective psychotic disorder. This study aimed to determine (1) potential differences in initiation rate and type of first antipsychotic medication between refugees, non-refugee migrants, second-generation migrants, and Swedish-born young adults with incident non-affective psychosis and (2) which sociodemographic and clinical factors are associated with initiation.
methodsThis register-based cohort included 12,960 adults aged 18-35 years, residing in Sweden during 2007-2018, with an incident diagnosis of a non-affective psychotic disorder in inpatient or specialised outpatient care. Sociodemographic and clinical factors associated with antipsychotic initiation were determined using modified Poisson regression models yielding Relative Risk, RRs, and 95% Confidence Intervals, CI.
resultsInitiation of antipsychotic use was slightly less common among refugees (65.6%) compared to non-refugee migrants (70.2%), second-generation migrants (71.0%), and Swedish-born individuals (71.1%). However, after adjustment for sociodemographic and clinical factors, there was no difference in initiation rates between refugees and Swedish-born individuals (adjusted RR 0.96; 95% CI 0.92-1.00). Olanzapine was most common initial antipsychotic in all groups. However, compared to the Swedish-born, refugees (1.47; 1.10-1.97), non-refugee migrants (1.70; 1.26-2.27) and second-generation migrants (1.43; 1.05-1.97) were more likely to initiate the use with long-acting injectable antipsychotics, and also with first-generation antipsychotics, particularly haloperidol. Sociodemographic factors associated with initiation were similar among refugees and Swedish-born individuals, including younger age, higher education and inpatient care.
conclusionOur finding that migrants were more likely to initiate long-acting antipsychotics suggests that clinical teams anticipate medication non-adherence among migrants.
