1 · What the graph read from it

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.

2 · The registry

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

Sunn pest is one of the most destructive insects in the western and central parts of Asia causing severe reductions of wheat yield and flour quality. Therefore, an effort was undertaken to find effective resistance by analyzing genetic variation among 25 wheat genotypes artificially infested in field-cages as well as using start codon targeted (SCoT) polymorphism and inter- retrotransposon amplified polymorphism (IRAP) markers. High variation was revealed amongst genotypes with Sunn pest resistance characteristics including Bayat, Bezostaya, Sayson, Line93, Line120, Rashagol, Golsepi and AarasGolsoor, which were classified as resistant to moderately resistant. SCoTs and IRAPs were determined as efficient markers for studying genetic diversity. The non-parametric Kruskal-Wallis test was conducted to evaluate the effect of specific SCoT and IRAP amplicons on Sunn pest resistance characteristics for wheat genotypes. The stepwise regression analysis exhibited seven informative SCoTs and IRAPs explaining the highest resistance characteristics variation ranging from 25.7-50.1 to 17.6-40.1, respectively. The relationship between resistance of genotypes and informative SCoT and IRAP amplicons was found based on canonical discriminant analysis showing the capacity of informative markers for functional marker selection method and screening the wheat germplasms for Sunn pest resistance characteristics.
