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
Food security remains a pressing global challenge, particularly for staple crops like rice. The traditional Yunnan landrace rice variety Mowanggu (MWG) exhibits broad-spectrum and durable resistance to Magnaporthe oryzae, the causal agent of destructive rice blast disease, making it a valuable germplasm resource for breeding. However, the molecular mechanisms underlying this resistance remain unclear due to the lack of a high-quality genome. Here, we present a chromosome-scale draft genome assembly of MWG, combining Nanopore long-read and Illumina short-read sequencing. Through comparative genomic analyses, we identified structural variations, gene family expansions and divergence events. We identified nine RLK genes within the Pi49 resistance locus, among which overexpression of OSAmwg_038136 enhanced the expression of pathogenesis-related genes and increased resistance to rice blast. OSAmwg_038136 was shown to interact with OsDIP1, a member of the R3H protein family, which positively regulates blast resistance. Our findings provide critical insights into the molecular basis of MWG durable blast resistance and offer a foundation for engineering broad-spectrum disease resistance in rice.
