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

Neuregulin 1 (NRG1) is one of the most promising candidate genes for schizophrenia. A number of replication studies have been conducted, although the results were inconsistent and no susceptible variant has yet been identified. The inconsistency might be attributed to the ethnic difference in allele and haplotype frequencies. However, it is equally possible that one or more genes interacting with NRG1 may also be implicated in schizophrenia and attribute to the inconsistency. To test the hypothesis, we conducted an interaction analysis between NRG1 and one of its receptor's (ERBB4) polymorphisms as well as the association analysis of the two genes associated with schizophrenia in Japanese. We observed no significant difference between patients and controls in allele frequencies or genotypic distributions of the 18 polymorphisms of the genes. The permutation test showed no significant differences in estimated haplotype frequencies between patients and controls, including the haplotype HAP(ICE). In the interaction analysis, significant interaction was observed between rs2919381 in NRG1 and rs7560730 in ERBB4 (P = 0.047, corrected). Thus, our results suggest the possibility that interaction between variants in NRG1 and ERBB4 might contribute to susceptibility for schizophrenia in a Japanese population. Further investigation may be necessary to confirm our results.
