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

This article reports on the allelopathic potential of Calotropis procera (Aiton) W.T. Aiton foliage on Handroanthus impetiginosus (Mart. ex DC.) Mattos. Predominant species in semiarid environments, especially in the Caatinga of the Northeast, where it acts as an invasive species. The leaves of C. procera were mixed with soil from the Caatinga and left to decompose for 90 days. The control group consisted only of soil from the Caatinga, Northeast, Brazil. The germination test was conducted in quadruplicate (30 seeds/treatment). For growth, 30 replicates per treatment were used, each with one seedling of the recipient species. The identification of the chemical constituents of C. procera was assessed by GC-MS. The data was submitted to the one-way ANOVA test. Residues from the decomposition of C. procera litter negatively affected seedling germination, with a reduction of up to 80% in the treatments evaluated. The phytochemical analysis showed the presence of 18 compounds, grouped into six main classes. Among the main compounds identified were: α-amyrin (C
