Article in Molecular biology reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers.
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
backgroundIn-vivo maternal haploids serve as the basis of doubled haploid (DH) breeding in maize. R1-navajo (R1-nj) gene governing anthocyanin colouration in the endosperm and embryo is widely used to identify haploid seeds. However, the expression of R1-nj depends on genetic-background of source-germplasm used for deriving DH-lines. Further, presence of C1-Inhibitor (C1-I) gene suppresses the expression of R1-nj, thus makes the selection of haploids difficult.
methodsIn the present study, 178 subtropically-adapted maize inbreds were crossed with two R1-nj donors 'that do not have haploid induction genes'. Of these, 76.4% inbreds developed purple colour in endosperm, while 23.6% did not show any colouration. In case of scutellum, 62.9% inbreds possessed colour and 37.1% were colourless. The anthocyanin intensity varied greatly, with 19.66% and 42.98% inbreds displayed the least intensity, while 16.85% and 0.84% inbreds showed the highest intensity in endosperm and scutellum, respectively. Two C1-I specific breeder-friendly markers (MGU-CI-InDel8 and MGU-C1-SNP1) covering (i) 8 bp InDel and (ii) A to G SNP, respectively, were developed. MGU-CI-InDel8 and MGU-C1-SNP1 markers predicted presence of C1-I allele with 92.9% and 84.7% effectiveness, respectively. However, when both markers were considered together, they provided 100% effectiveness.
conclusionsThese markers of C1-I gene would help in saving valuable resources and time during haploid induction in maize. The information generated here assume great significance in DH breeding of maize.
