Efficacy and safety of prophylactic use of benzhexol after risperidone treatment.
Article in Heliyon, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
To test the effect of prophylactic use of benzhexol in schizophrenia patients after risperidone treatment. Sixty-nine drug naïve schizophrenia patients were recruited. All patients were administered risperidone. Patients in the benzhexol group were given a benzhexol tablet of 2 mg bid daily. The controls received a placebo tablet of 2 mg bid daily. The primary outcome measured using the Extrapyramidal Symptoms Rating Scale (ESRS). The Positive and Negative Syndrome Scale (PANSS) and the Brief Psychiatric Rating Scale (BPRS) measured secondary outcome. There were significant time and group effects on the ESRS scores of the two groups. The post hoc analysis yielded significant differences at 1, 2, 4, and 8 weeks between the two groups. There was a significant time effect on the PANSS scores of the two groups. No significant group and interaction effects on the PANSS scores of the two groups. There was a significant time effect on the BPRS scores of the two groups. No serious adverse events were found in this study. Prophylactic use of benzhexol reduced extrapyramidal symptom in schizophrenia patients after risperidone treatment and did not affect the antipsychotic action of risperidone.
