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
key messageA point mutation in the AHAS1 gene leading to resistance to imidazolinone in chickpea was identified. The resistance is inherited as a single gene. A KASP marker targeting the mutation was developed. Weed control in chickpea (Cicer arietinum L.) is challenging due to poor crop competition ability and limited herbicide options. A chickpea genotype with resistance to imidazolinone (IMI) herbicides has been identified, but the genetic inheritance and the mechanism were unknown. In many plant species, resistance to IMI is caused by point mutation(s) in the acetohydroxyacid synthase (AHAS) gene resulting in an amino acid substitution preventing herbicide attachment to the molecule. The main objective of this research was to characterize the resistance to IMI herbicides in chickpea. Two homologous AHAS genes namely AHAS1 and AHAS2 sharing 80 % amino acid sequence similarity were identified in the chickpea genome. Cluster analysis indicated independent grouping of AHAS1 and AHAS2 across legume species. A point mutation in the AHAS1 gene at C675 to T675 resulting in an amino acid substitution from Ala205 to Val205 confers the resistance to IMI in chickpea. A KASP marker targeting the point mutation was developed and effectively predicted the response to IMI herbicides in a recombinant inbred (RI) population of chickpea. The RI population was used in molecular mapping where the major locus for the reaction to IMI herbicide was mapped to chromosome 5. Segregation analysis across an F2 population and RI population demonstrated that the resistance is inherited as a single gene in a semi-dominant fashion. The simple genetic inheritance and the availability of KASP marker generated in this study would speed up development of chickpea varieties with resistance to IMI herbicides.
