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

This study investigated the impact of salinity stress and cytokinin application on quinoa (Chenopodium quinoa Willd.) seed quality, germination behavior, and gene expression. Four quinoa cultivars with differing salinity tolerance were evaluated under varying salinity levels (0, 25, 40 dS m⁻¹) and cytokinin treatment (0 and 0.75 µM 6-BA). Seed germination was assessed under multiple water potentials, and the hydrotime model was applied to quantify responses. Salinity during maternal growth significantly influenced progeny seed quality, with some cultivars-particularly the salt-tolerant 'Titicaca'-exhibiting enhanced germination performance under stress. Cytokinin foliar application further improved germination rates, particularly in salt-sensitive genotypes, by modulating key hydrotime parameters; for instance, the base water potential (Ψ
