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

Calotropis procera (Akra, 2n = 22) is a fast-growing, fiber-producing, and climate-resilient, yet underexplored for domestication. The significant step forward in the domestication of this invaluable plant species marks the development of a reference genome. The study reveals a chromosome-scale genome that anchors 11 chromosomes, with a reference assembly spanning approximately 202.83 Mb. It contains few repetitive sequences, accounting for only 5% of the total genome. C. procera display a significant pair-orthology dN/dS ratio of nearly 0.2 to 0.25, indicating strong conservation, purifying selection, and resistance to harsh conditions. C. procera experienced phylogenetic relations with familiar sister genera divergent around 38.5 million years ago. The chromosomal structural rearrangement endured alterations throughout divergence due to a synteny interaction with the genomes of A. syriaca. The findings delve into the role of gene families in the adaptive evolutionary processes of C. procera. The study enhanced our comprehension of genome biology, the influence of gene families on adaptation. The genome research is invaluable and will significantly influence the future domestication of C. procera.
