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

Histone proteins are integral part of chromatin and their expression is typically linked to DNA replication in the S phase of cell cycle. Histone H3 is one of the four histones, along with H2A, H2B and H4, which forms the eukaryotic nucleosome octomer core. Using differential display of mRNA and rapid amplification of cDNA ends (RACE), a full-length Histone H3.1 cDNA (CsH3) was isolated from tea leaves. The open reading frame consisted of 411 nucleotides and deduced amino acid sequence comprised of 136 amino acid residues. CsH3 shared 79-82% and 98% identity at nucleotide and amino acid sequences, respectively with Histone H3 isolated from other plant species. During active-growth period of tea, higher expression was observed in apical buds that decreased gradually with increasing age of the leaf. During dormancy season, the expression of CsH3 was severely down-regulated in all the leaves studied. CsH3 was found to be down regulated in response to drought stress and ABA treatment and up-regulated by GA(3) treatment. A positive association of CsH3 abundance with active cellular growth suggested its role in plant growth and development.
