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

Common strains of wildtype zebrafish (Danio rerio) have unique genomic features including SNPs and CNV, but strain information often goes unreported in the literature. As a result, the confounding effects of interstrain variation makes repetition of studies in zebrafish challenging. Here we analyze hepatic mRNA expression patterns between three common zebrafish strains (AB, Tuebingen (TU), and WIK) using Agilent 4 × 44 K gene expression microarrays to establish baseline mRNA expression across strains and between sexes. We observed wide variation in sex-specific gene expression within AB and WIK strains (141 genes in AB and 67 genes in WIK), but no significant variation between sexes within TU. After partitioning the dataset into male and female subsets, we detected 421 unique mRNA transcripts with statistically significant differential expression; 269 mRNA transcripts varied between males, 212 mRNA transcripts varied between females, and 59 mRNA transcripts varied across the three strains, regardless of sex. It is not surprising that mRNA expression profiles differ between sexes and strains, but it is imperative to characterize the differences. These results highlight the complexity of variation within zebrafish and underscore the value of this model system as a valid representation of normal variation present in other species, including humans.
