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
Malate impacts fruit acidity and plays a vital role in stress tolerance. Malate accumulation is induced by salinity in various plants as a metabolite in coping with this stress. However, the exact molecular mechanism responsible for salinity-induced malate accumulation remains unclear. Here, we determined that salinity treatment induces malate accumulation in pear (Pyrus spp.) fruit, calli, and plantlets compared to the control. Genetic and biochemical analyses established the key roles of PpWRKY44 and ABRE-BINDING FACTOR3 (PpABF3) transcription factors in promoting malate accumulation in response to salinity. We found that PpWRKY44 is involved in salinity-induced malate accumulation by directly binding to a W-box on the promoter of the malate-associated gene aluminum-activated malate transporter 9 (PpALMT9) to activate its expression. A series of in-vivo and in-vitro assays revealed that the G-box cis-element in the promoter of PpWRKY44 was targeted by PpABF3, which further enhanced salinity-induced malate accumulation. Taken together, these findings suggest that PpWRKY44 and PpABF3 play positive roles in salinity-induced malate accumulation in pears. This research provides insights into the molecular mechanism by which salinity affects malate accumulation and fruit quality.
