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

Water deficit stress, exacerbated by climate change, severely limits crop and medicinal plant productivity. This study evaluated the effects of foliar-applied ascorbic acid (AsA) and salicylic acid (SA) (0, 1, and 2 mM) under varying water deficit levels (90%, 60%, and 30% field capacity (FC)) on antioxidant responses, growth, and essential oil content of marjoram. The treatment ranking results, using the multivariate MGIDI index, showed a statistically significant difference between the treatments. The four selected treatments, were T13, T16, T17, and T18. Mean comparisons revealed that increased stress severity significantly reduced shoot fresh and dry weight (FW and DW), photosynthetic pigment content, and stem height (SH). Under drought stress, essential oil percentage (EO (%)) and the activities of total superoxide dismutase (T-SOD), and its isozymes (Fe-SOD, Cu/Zn-SOD, and Mn-SOD), catalase (CAT), guaiacol peroxidase (GPX), and ascorbate peroxidase (APX) exhibited an initial increase, followed by a decline at higher stress intensities. Concurrently, increasing stress led to a reduction in essential oil yield (EOY), whereas hydrogen peroxide (H
