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

MAIN

conclusionThis study establishes a genotype-specific transformation system for indica rice cultivars Ranjit, Mahsuri, and Kon Joha using 35S:RUBY and CRISPR/LbCas12a constructs, enabling functional genomics studies and genetic improvement. The indica rice subspecies generally faces challenges in functional genomics and genetic improvement due to its recalcitrance to tissue culture and Agrobacterium-mediated transformation. Three indica rice varieties, Ranjit, Mahsuri, and Kon Joha, cultivated in Assam (India) were selected to optimize callus induction, regeneration, and genetic transformation. Ranjit and Mahsuri are high-yielding cultivars, whereas Kon Joha is an indigenous aromatic landrace of high commercial value. Initially, key steps, such as callus induction and regeneration, were optimized for Ranjit and Kon Joha using mature seed. Thereafter, for transformation, immature embryos were selected as explants because of their competence for agro-infection. The highest callus induction frequency of 70.33% and 90% was achieved with 3.0 and 3.5 mg L
