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

Maintaining the balance between growth and drought tolerance is arguably one of the most prevalent challenges encountered by woody plants. In this study, we performed genome-wide association studies (GWAS) of percentage loss of diameter (PLD) in the stems of 300 Populus tomentosa accessions under drought stress. Our analysis identified the bZIP transcription factor PtobZIP18 as a key regulator of xylem development in response to drought stress. PtobZIP18 directly increased the expression of PtoGATL3, PtoCESA3 and PtoDUF1635, thereby influencing wood composition and vessel density. Under well-watered conditions, PtobZIP18 regulated the formation of significantly larger stem diameters. Conversely, PtoCIPK9 and PtoWRKY19 synergistically reduced PtobZIP18 protein levels by modulating its stability and transcription, thereby regulating water transport capacity under drought stress. Furthermore, a 110-bp structural variation (SV) and three single-nucleotide polymorphisms (SNPs) in the PtobZIP18 promoter divided the natural population into two haplotypes (PtobZIP18
