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

C2H2-type zinc finger transcription factors play crucial roles in regulating plant growth and responses to abiotic stresses. Although pear is an economically important fruit crop with available genomic resources, the comprehensive analyses of its C2H2 gene family remain limited. In this study, we performed a genome-wide identification of C2H2 genes in pear, identifying 52 members that were unevenly distributed across 17 chromosomes. The predicted PyC2H2 proteins ranged from 343 to 1764 amino acids in length, with molecular weights between 12.4 and 62.7 kDa. Phylogenetic analysis classified these 52 PyC2H2 proteins into 10 classical clades, where genes with closer evolutionary relationships shared more similar conserved motifs. Collinearity analysis identified 37 collinear gene pairs between
