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

backgroundIncreasing selection of herbicide-resistant weed biotypes has intensified the search for alternatives to the intensive use of synthetic herbicides. Among these alternatives, essential oils (EO) have attracted attention because of their allelopathic potential and low environmental impact. This study evaluated the effects of different doses of EOs extracted from orange (Citrus sinensis) by hydrodistillation and steam distillation, and from citronella (Cymbopogon nardus and C. winterianus), on the germination and early development of Eleusine indica, Digitaria insularis, Euphorbia heterophylla, and Amaranthus hybridus.

resultsThe EOs analyzed were characterized primarily by oxygenated monoterpenes and terpene hydrocarbons, notably citronellol, citronellal, geraniol and limonene. Citronella EOs caused strong inhibition of germination and vigor, resulting in near-total seedling suppression from 10 mL L

conclusionsThe combined results indicate that citronella EOs exhibit high bioactivity and stand out as promising candidates for bioherbicide development, whereas orange EOs show a less intense but relevant allelopathic effect, supporting their potential use as complementary tools in sustainable weed management strategies. © 2026 The Author(s).
