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

rationaleThere is a debate about whether doctors should prophylactically use benzhexol in schizophrenic patients to reduce the occurrence of extrapyramidal side effects (EPS) after risperidone treatment.

objectivesWe conducted a prospective animal model to explore the efficacy and safety of the prophylactic use of benzhexol after risperidone treatment and the mechanism of the process.

methodsC57/BL mice were injected with MK-801 (0.5 mg/kg, i.p.) once a day for two weeks. The open field test (OFT) and the novel object recognition test (NORT) assessed the schizophrenia-like behavior of mice. After four weeks of treatment with benzhexol (10 mg/kg, i.g.) and risperidone (3 mg/kg, i.g.), the inclined screen test (IST), rotarod test (RT), open field test (OFT), novel object recognition test (NORT) and the Morris water maze test (MWM) were conducted successively. The expression of BDNF, p-Tau, and Tau in the hippocampus was detected by Western blot assay.

resultsWe showed that benzhexol can significantly attenuate risperidone-induced motor coordination impairments and catalepsy and did not affect the efficacy of risperidone in reducing spontaneous activity. Notably, the prophylactic use of benzhexol reduced the recognition memory and spatial memory in MK-801-induced model mice after risperidone. In addition, benzhexol increased the ratio of p-Tau/Tau and decreased BDNF expression levels in the hippocampus.

conclusionsWe found that the prophylactic use of benzhexol can reduce the occurrence of EPS and does not affect the efficacy of risperidone in the treatment of positive symptoms. Benzhexol may impair cognitive function but did not cause further deterioration of cognitive function in MK-801 mice.
