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 major QTL (QLr.cau-2BL) for APR to leaf rust was detected on 2BL; an SSR marker was developed to closely link with QLr.cau-2BL and validated for effectiveness of MAS. The wheat landrace Hongmazha (HMZ) possesses adult plant resistance (APR) to leaf rust. To detect and validate quantitative trait locus (QTL) for the APR, four wheat populations were assessed for leaf rust severity in a total of eight field and greenhouse experiments. The mapping population Aquileja × HMZ (120 recombinant inbred lines, RILs) was genotyped using 90 K SNP markers. A major QTL (QLr.cau-2BL) was detected between the markers IWB3854 and IWB21922 on chromosome 2BL. IWB3854 and IWB21922 were positioned at approximately 531.14 Mb and 616.48 Mb, respectively, on 2BL of IWGSC RefSeq v1.0 physical map. Based on the sequences between 531.14 and 616.48 Mb on 2BL of IWGSC RefSeq v1.0, 415 simple sequence repeat (SSR) markers were developed. These markers and 28 previously published SSR makers were screened; the resulted polymorphic markers were used to genotype the relatively larger population RL6058 × HMZ (371 RILs). QLr.cau-2BL was mapped within a 1.5 cM interval on 2BL map of RL6058 × HMZ, and a marker (Ta2BL_ssr7) was identified to closely link with QLr.cau-2BL. Effectiveness of selection for QLr.cau-2BL based on Ta2BL_ssr7 was validated using two populations (RL6058 × HMZ F
