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
Heterosis is extensively used in the 2-line hybrid breeding system. Photosensitive/thermosensitive genic male sterile (P/TGMS) lines are key components of 2-line hybrid rice, and TGMS lines containing tms5 have significantly advanced 2-line hybrid rice breeding. We cloned the TMS5 gene and found that TMS5 is a tRNA cyclic phosphatase that can remove 2',3'-cyclic phosphate (cP) from cP-ΔCCA-tRNAs for efficient repair to ensure maintenance of mature tRNA levels. tms5 mutation causes increased levels of cP-ΔCCA-tRNAs and reduced levels of mature tRNAs, leading to male sterility at restrictive temperatures. However, the regulatory network of tms5-mediated TGMS remains to be clarified. Here, we demonstrate that the E3 ligase OsHel2 cooperates with TMS5 to regulate TGMS at restrictive temperatures. Consistently, both the accumulation of cP-ΔCCA-tRNAs and the reduction in mature tRNAs in the tms5 mutant are largely recovered in the tms5 oshel2-1 mutant. A lesion in OsHel2 results in partial readthrough of the stalled sequences, thereby enabling evasion of ribosome-associated protein quality control (RQC) surveillance. Our findings reveal a mechanism by which OsHel2 impedes readthrough of stalled mRNA sequences to regulate male fertility in TGMS rice, providing a paradigm for investigating how disorders in components of the RQC pathway impair cellular functions and lead to diseases or defects in other organisms.
