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

Schizophrenic patients treated with atypical antipsychotics (AAPs) often develop excessive body weight gain, which may lead to further morbidity and poor treatment compliance. This study examined whether genetic variants in the brain-derived neurotrophic factor (BDNF) gene may be associated with body weight change after AAP treatment. The study included 481 schizophrenic patients treated with clozapine (n = 266), olanzapine (n = 79), or risperidone (n = 136) for an average of 49.2 ± 28.2 months. Three common single-nucleotide polymorphisms (SNPs) of the BDNF gene were chosen as tagging SNPs. In single-marker-based analysis, the BDNF rs11030101-T homozygous genotype was found to be associated with significantly increased body weight gain (P = 0.037). The BDNF Val66Met (rs6265) polymorphism was not found to be associated with body weight gain. Haplotype analysis further showed that the rs11030101-T-allele-related haplotype is also associated with increased body weight gain (P = 0.047). Our findings suggest that there is a nominal association with rs11030101 but did not replicate the previously found relationship between the BDNF Val66Met polymorphism and body weight gain during long-term AAP treatment.
