The association of 20 short tandem repeat loci of autosomal chromosome with male schizophrenia.
Article in Brain and behavior, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionSchizophrenia's heritability and familial transmission have been known for several decades. The male-specific Y chromosome plays an important role in schizophrenia. Short tandem repeats (STRs)have been recognized as risk genes in the development of schizophrenia. Here, we investigated the association between male schizophrenia and Y-chromosomal STRs loci.
methodsWe recruited 355 patients with schizophrenia and 473 healthy males for physical examination and amplified them with a PowerPlex 21 System fluorescence-labeled composite amplification System. Then, the resultant products were separated by electrophoresis and further detected. Finally, differences in allele and genotype frequency distributions of STR loci were observed.
resultsOur results showed that all 20 STR loci were in accordance with Hardy-Weinberg's law (p > .05). There were statistically significant differences in alleles of D13S317 and D5S818 loci and genotype frequency distribution between the two groups (alleles: p = .039, p = .022, respectively; genotype: p = .0004, p = .011, respectively). However, there was no difference in the other autosomal 18 STR loci between the two groups (p > .05). Univariate analysis showed that the frequency distribution differences of allele 11 and genotype 10-11 at the D13S317 locus between the two groups were significant (compared to the controls, p = 0.005, odds ratio (OR) = 1.37, 95%b confidence interval (CI) = 1.10-1.71, compared to the controls, p = .0000002, OR = 3.92, 95% CI = 2.27-6.77, respectively). The frequency distribution differences of allele 7 and genotype 7-10 at D5S818 between the two groups were significant (compared to the controls, p = .0006, OR = 3.42, 95% CI = 1.63-7.16, compared to the controls, p = .0011, OR = 8.24, 95% CI = 1.83-37.05, respectively).
conclusionPolymorphisms of the D13S317 and D5S818 loci may be predisposing factors for schizophrenia.
