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
White lupin (Lupinus albus L.) is an ancient grain legume that is still undergoing improvement of domestication traits, including vernalization-responsiveness, providing frost tolerance and preventing winter flowering in autumn-sowing agriculture, and vernalization-independence, conferring drought escape by rapid flowering in spring-sowing. A recent genome-wide association study highlighted several loci significantly associated with the most contrasting phenotypes, including deletions in the promoter of the FLOWERING LOCUS T homolog, LalbFTc1, and some DArT-seq/silicoDArT loci. The present study aimed to develop and validate a versatile PCR marker array enabling molecular selection of spring- and winter-type white lupin ecotypes. Candidate DArT-seq and silicoDArT loci were transformed into cleaved amplified polymorphic sequence (CAPS) or derived CAPS markers. Developed markers, together with those previously published for LalbFTc1 INDELs and quantitative trait loci from linkage maps, were implemented for screening of white lupin germplasm panel subjected to 2-year phenotyping of phenology traits. Three DArT-seq, two silicoDArT and seven LalbFTc1 INDEL markers were positively validated, constituting a convenient PCR-based marker assay for rapid and accurate reselection of white lupin germplasm towards early flowering and thermoneutrality or late flowering and vernalization-responsiveness, as well as for tracking high genetic and phenotypic diversity within white lupin landraces, revealed in the present study.
