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

Two ventricular myosin heavy chains (MHCs), alpha and beta, which exhibit different levels of ATPase activity, are differentially expressed during development, in response to thyroid hormone and in several pathological conditions. We have isolated and analyzed the structure of the genes coding for alpha- and beta-MHC mRNAs in the rat. Detailed analysis of eight overlapping MHC genomic clones shows that the alpha- and beta-MHC genes are organized in tandem and span 50 kilobases of the chromosome. The beta-MHC gene, predominantly expressed in late fetal life, is located 4 kilobases upstream from the alpha-MHC gene, predominantly expressed in the adult. These two genes are very closely related at the nucleotide sequence level, suggesting that they have arisen by duplication of a common ancestor, yet their expression in the ventricular myocardium has been shown to be regulated in an antithetic fashion by thyroid hormone.
