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

High seed production makes Sporobolus indicus var. pyramidalis a difficult to control invasive grassland plant. The objective of the present study was to investigate the bioactivity of Cyperus rotundus, Phyllanthus tenellus and Ricinus communis green leaf extracts and of Carica papaya seeds on S. indicus germination without breaking dormancy, simulating the field conditions. The ethanolic extract bioactivity of C. rotundus, P. tenellus, R. communis green leaves and C. papaya seeds, at concentrations of 25, 50 and 75% in S. indicus germination was evaluated. Carotenoids, flavonoids, soluble phenolic compounds and total tannins were quantified in the extracts. The chemical component concentrations varied between alcoholic extracts. The P. tenellus extracts at all dilutions and those of R. communis and C. papaya at 75% completely suppressed S. indicus seed germination at five and ten days which can be attributed to their high tannin concentration, total phenolic compounds and flavonoids.
