Effectiveness of antipsychotic medication in patients with schizophrenia in a real world retrospective observational study in Ethiopia.
Observational study in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Antipsychotic medications have become the cornerstone of treatment for schizophrenia. The antipsychotic drugs are high-affinity antagonists of dopamine D2 receptors that are most effective against psychotic symptoms, but antipsychotic drugs can have side effects that overshadow their advantages, like sedation, extrapyramidal symptoms, and weight gain, which are often experienced as adverse effects. In our country, the relative effectiveness of antipsychotic medication as well as their tolerance in schizophrenia patients is not fully addressed. This study aims to determine the effectiveness of antipsychotic medication and associated factors in schizophrenia patients at the psychiatry clinic. An institutional-based retrospective cohort study was conducted using administrative data of patients with schizophrenia disorder based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR) that initiated or changed to a new antipsychotic treatment by clinicians assessments from April 1, 2023, to March 1, 2024 at university of Gondar specialized hospital. The effectiveness of prescribed antipsychotic medication was evaluated using the Clinical Global Impressions-Schizophrenia scale (CGI-SCH), inclusive of subscales for positive, negative, depressive, and cognitive symptoms. A total of 608 patients were receiving antipsychotic medications as follows: 118 patients (19.4%) were prescribed haloperidol, 88 patients (14.5%) were taking chlorpromazine, 48 patients (7.9%) received fluphenazine (decanoate), 126 patients (20.7%) were on risperidone, and 228 patients (37.5%) were treating with olanzapine. In total, 64.8% of patients show improvement in the prescribed medications within one year of treatment (Kaplan-Meier estimate 35.2%) for haloperidol, 31 (26.3%) for chlorpromazine, 30 (34.1%) for Fluphenazine, 19 (39.6%) for risperidone, 51 (40.5%), and 83 (36.4%) for olanzapine. Effectiveness was assessed using the Clinical Global Impressions-Improvement (CGI-I); the overall improvements like negative, positive, depressive, and cognitive symptoms were significantly higher for olanzapine, followed by haloperidol (p < .001). Good adherence (AHR = 0.63; 95% CI 0.5-0.78), history of relapse (AHR = 1.43; 95% CI 1.13-1.82), unemployment (AHR = 1.4; 95% CI 1.06-1.85), and history of suicidal ideation (AHR = 1.79; 95% CI 1.24-2.58) were significant predictors of symptoms improvement. The study found olanzapine is more effective in improving schizophrenia symptoms than other antipsychotic drugs. Medication adherence, symptom relapse, and suicidal thoughts significantly impacted antipsychotic effectiveness in individuals with schizophrenia disorder.
