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.
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
Introduction: Brinjal is an essential solanaceous vegetable crop that can be cultivated globally in tropical and subtropical regions. Despite its economic significance, productivity is frequently limited by a narrow genetic base and by the under-exploitation of hybrid vigor. In order to determine superior hybrids with high yield and desirable quality traits suitable for tropical environments, the current study sought to assess the heterotic potential, combining ability, and stability of brinjal genotypes. Methods: A total of 28 F Results: All traits showed significant genotype variation, indicating a high level of genetic diversity. BL-2011-219-8-1 and SL-8-PB-1-3-1-4 showed superior general combining ability for a variety of yield and quality characteristics among the parents. With better specific combining ability and heterotic performance in all environments, the hybrid Pusa Purple Long × BL-219 had the highest fruit yield (548.02 q ha Discussion: The findings indicate the involvement of both additive and non-additive gene actions in controlling brinjal yield and associated traits. The presence of additive effects suggests that selection-based breeding approaches may be effective for the improvement of certain traits in early or advanced generations, whereas the predominance of non-additive effects for some characteristics highlights the importance of heterosis breeding and hybrid development. In particular, the hybrid Pusa Purple Long × BL-219 exhibited high productivity and stability across three seasons, indicating its potential for commercial hybrid cultivation and its usefulness as a suitable parental combination in future breeding programs.
