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

key messageStrigolactones mitigate Cr(VI) toxicity in Capsicum annuum by limiting chromium uptake and reprogramming photosynthesis and redox metabolism, thereby preserving chloroplast function and cellular integrity. Agricultural soil contamination and its impact on the crops require alternative strategies to reduce associated environmental risks. Strigolactones (SLs) are emerging phytohormones that regulate plant development and stress adaptation; however, their role in hexavalent chromium [Cr(VI)] tolerance remains poorly understood. Here, we investigated the mechanistic basis of SL-mediated mitigation of Cr(VI) toxicity in Capsicum annuum using the synthetic analog rac-GR24. Cr(VI) stress severely impaired photosynthetic performance by disrupting photosystem efficiency, suppressing Calvin-Benson cycle enzyme activities, and reducing ATP and NADPH production, leading to excessive reactive oxygen species accumulation and cellular damage. rac-GR24 markedly decreased Cr uptake and restored photosynthetic carbon metabolism by enhancing the expression of key Calvin cycle enzymes and genes such as RbcS, RbcL, PGK, GAPDH, and PRK. The regulation of fluorescence parameters such as Fv/Fm, Ф
