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 messageWe identified a pivotal transcription factor TaABI5-A4 that is significantly associated with pre-harvest sprouting in wheat; its function in regulating seed dormancy was confirmed in transgenic rice. ABI5 is a critical transcription factor in regulation of crop seed maturation, dormancy, germination, and post-germination. Sixteen copies of homologous sequences of ABI5 were identified in Chinese wheat line Zhou 8425B. Cultivars of two haplotypes TaABI5-A4a and TaABI5-A4b showed significantly different seed dormancies. Based on two SNPs between the sequences of TaABI5-A4a and TaABI5-A4b, two complementary dominant sequence-tagged site (STS) markers were developed and validated in a natural population of 103 Chinese wheat cultivars and advanced lines and 200 recombinant inbred lines (RILs) derived from the Yangxiaomai/Zhongyou 9507 cross; the STS markers can be used efficiently and reliably to evaluate the dormancy of wheat seeds. The transcription level of TaABI5-A4b was significantly increased in TaABI5-A4a-GFP transgenic rice lines compared with that in TaABI5-A4b-GFP. The average seed germination index of TaABI5-A4a-GFP transgenic rice lines was significantly lower than those of TaABI5-A4b-GFP. In addition, seeds of TaABI5-A4a-GFP transgenic lines had higher ABA sensitivity and endogenous ABA content, lower endogenous GA content and plant height, and thicker stem internodes than those of TaABI5-A4b-GFP. Allelic variation of TaABI5-A4-affected wheat seed dormancy and the gene function was confirmed in transgenic rice. The transgenic rice lines of TaABI5-A4a and TaABI5-A4b had significantly different sensitivities to ABA and contents of endogenous ABA and GA in mature seeds, thereby influencing the seed dormancy, plant height, and stem internode length and diameter.
