Antipsychotic polypharmacy and associated factors among patients with schizophrenia: Multicenter cross-sectional study in Northwest Ethiopia.
Article in PloS one, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundAntipsychotic polypharmacy (APP) remains common despite guideline recommendations to minimize combinations, except after repeated antipsychotic monotherapy trials. This study aimed to assess APP and its associated factors among schizophrenia patients at comprehensive specialized hospitals in Northwest Ethiopia.
methodsAn institutional-based cross-sectional study was conducted among 422 schizophrenia patients at selected hospitals in Ethiopia from June to August 2022. The data were collected using a semi-structured questionnaire. Study participants were enrolled using systematic random sampling. Data entry and analysis were done with Epi-data version 4.6.1 and SPSS version 24, respectively. APP was determined by reviewing the number of medications based on relevant evidence. A multivariable logistic regression model was fitted to identify APP factors. Variables with a p-value of < 0.05 at a 95% confidence interval were considered statistically significant.
resultsFrom a total of 430 approached samples, 422 (98.1% response rate) eligible patients were included in the study. An overall APP prevalence was 22.7% (95% CI: 19-27). Duration of illness (AOR = 2.88; 95% CI: 1.49, 5.59); duration of treatment (AOR = 3.79; 95% CI: 1.05, 13.62); number of admissions (AOR = 4.93; 95% CI: 2.52, 9.64); and substance use (AOR = 2.58; 95% CI: 1.49, 4.47) were significantly associated with APP. CONCLUSION AND RECOMMENDATION: In this study, APP was recorded in a considerable number of patients. Patients with a longer duration of illness and treatment, frequent admissions, and substance users need critical follow-up to minimize antipsychotic medication use.
