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

The increasing resistance of Helicoverpa armigera to currently deployed Bacillus thuringiensis (Bt) genes in transgenic crops necessitates the development of new insecticidal genes that can effectively control this pest. This study evaluates the in-planta efficacy of cry1Ac34, a truncated, plant codon-optimized gene derived from an Indian Bt isolate (SK-783). The cry1Ac34 gene was successfully introduced into Nicotiana tabacum through Agrobacterium-mediated transformation. Following the transformation, PCR-positive T
