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
Requirement of vernalization is an important factor which plays a crucial role in cereals to transit from vegetative to reproductive phase. There are three types of growth habit in barley: winter, spring and facultative types; in which spring type does not require vernalization but winter and facultative genotypes require full and partial vernalization, respectively. Combination of two loci, Vrn-h1 and Vrn-h2, regulates vernalization in barley genotypes. Specific DNA markers have been identified for growth habit regulator genes in barley. In this study, we examined 24 barley genotypes using specific primers for detecting Vrn-h1and Vrn-h2 loci. Results showed that among all differently suggested primer combinations, a few markers were precisely correlated with seasonal growth habit in barley. The specific markers of 600, 600 and 200 bps were verified for ZCCT-Ha, ZCCT-Hb and ZCCT-Hc loci, respectively. Our field growth habit test showed that cultivar Bahman as a winter growth habit, where all the others genotypes exhibited spring growth habit. By using specific primers for Vrn-h1, only Bahman cultivar produced 616 bp and 830 bp fragments and spring genotypes showed 574 bp or 616 bp alleles without any amplification for 830 bp fragments. Therefore, presence of 616 bp and 830 bp alleles together in each genotype can be considered as an informative marker for winter growth habit in barley. These informative markers can be used easily in barley breeding programmes for detection of growth habit types in the seedling stage.
