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

Drought stress limits growth, essential oil production, and menthol biosynthesis in peppermint (Mentha piperita). Plant growth-promoting rhizobacteria (PGPR), such as Pseudomonas fluorescens, can act as a biotic factor to enhance plant growth, antioxidant defense, and secondary metabolite accumulation under water stress. This study investigated the effects of P. fluorescens strain 18 inoculation on growth, antioxidant activity, essential oil composition, and menthol biosynthesis gene expression under three drought levels (30%, 65%, and 100% field capacity). Under drought stress at 65% field capacity, bacterial inoculation resulted in a 21.4% increase in shoot dry weight and a 29.8% increase in root dry weight. Bacterial inoculation also enhanced the activity of antioxidant enzymes peroxidase (POD), superoxide dismutase (SOD), and catalase (CAT) this reducing hydrogen peroxide (H
