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.
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
key messageOur study is the first to demonstrate that PSK1 , a SKP1 -like gene homologue, is involved in salinity tolerance. Our functional characterization of PSK1 provides new insights into tree peony development. A homologous gene of S-phase kinase-associated protein1 (SKP1) was cloned from tree peony (Paeonia suffruticosa) and denoted as PSK1. The 462-bp open reading frame of PSK1 was predicted to encode a protein comprising 153 amino acids, with a molecular mass of 17 kDa. The full-length gene was 1,634 bp long and included a large 904-bp intron. PSK1 transcription was detected in all tissues, with the highest level observed in sepals, followed by leaves. Under salinity stress, overexpression of PSK1 in Arabidopsis resulted in increased germination percentages, cotyledon greening, and fresh weights relative to wild-type plants. Furthermore, transgenic Arabidopsis lines containing 35S::PSK1 displayed increased expression of genes that would be essential for reproduction and growth under salinity stress: ASK1, LEAFY, FT, and CO involved in flower development and flowering time as well as P5CS, RAB18, DREB, and SOD1-3 contributing to salinity tolerance. Our functional characterization of PSK1 adds to global knowledge of the multiple functions of previously explored SKP1-like genes in plants and sheds light on the molecular mechanism underlying its role in salinity tolerance. Our findings also provide information on the function and molecular mechanism of PSK1 in tree peony flower development, thereby revealing a theoretical basis for regulation of flowering and conferral of salinity tolerance in tree peony.
