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

Dracocephalum kotschyi is a medicinal plant rich in antioxidant phytochemicals. Identifying the suitable cultivation region and evaluating the impact of environmental factors can help in choosing the best conditions for the commercial production of these herbs. The present study investigated the effect of different cultivation areas, Lasak (LSK), Saravarsu (SVS), and Sorkh Geriveh (SGV) on the glandular trichome density and phytochemicals of D. kotschyi. According to the findings, the environmental factors significantly affected the plant phytochemicals. The highest glandular trichome density (16 number mm−2), essential oil content and yield (0.716% and 0.45 g m−2), geraniol (24.3%), citral (16.2%), cis-carveol (13.2%), α-pinene (12%), methyl generate (7.2%), geranyl acetate (7.1%), PAL activity (10.104 nmol min−1 g−1 FW), total phenol (2.036 mg GAE g−1 DW), coumaric acid (0.112 mg g−1 DW), rutin (29.688 mg g−1 DW), rosmarinic acid (9.668 mg g−1 DW) and apigenin (8.089 mg g−1 DW) were recorded in the SGV region so that was up to 100-fold higher than in the LSK region. Finally, the environmental conditions of the SGV region (higher altitude, lower temperature, rainfall, and humidity, as well as some soil characteristics) strongly increased the production of phytochemicals, so this region is suggested for the commercial production of this plant and its secondary metabolites for various industries.
