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

As essential plant hormones, gibberellins (GAs) regulate various growth and development processes. GA oxidases (GAoxs), including the GA2ox, GA3ox, and GA20ox subgroups, play prominent roles in the synthesis and degradation of GA; however, a systematic analysis of GAoxs has not been reported in sweet potato. Here, we identified GAox genes based on a comparative genomic analysis in sweet potato (I.batatas) and its two diploid wild relatives I. trifida and I. triloba. A total of 71 GAox genes were identified, with 23 in sweet potato, 25 in I. trifida and 23 in I. triloba. These genes can be divided into four phylogenetic groups based on their protein sequences. Each subgroup had their own conserved motif combination. The prediction of cis-elements in the promoter region showed that the most numerous elements in the promoter regions were related to hormone response. GAox genes in sweet potato respond to both plant hormones and abiotic stresses; notably, gene expression and co-expression analysis implicated ibGA2ox10 in tuber expansion, ibGA20ox3/ibGA3ox5 in indole-3-acetic acid (IAA) and gibberellin (GA) synergy, ibGA2ox5/ibGA3ox7 in gibberellin (GA) and paclobutrazol antagonism, and ibGA20ox1/ibGA3ox8 in abiotic stress response.
