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
Background: Osteonecrosis of the femoral head (ONFH) is an ischemic disease characterized by the impairment of angiogenesis. We have previously elucidated the role of tsRNAs and BMSC exosomes in ONFH, but whether tsRNA-modified BMSC exosomes promote angiogenesis in ONFH remains unclear. Methods: The expression of angiogenesis-related tsRNA in plasma exosomes from ONFH patients was examined by q-PCR. The function of tsRNA in HUVECs was identified by CCK-8 and angiogenesis assay. Exosomes purified from tsRNA-15797 overexpressed BMSCs were cocultured with HUVECs to examine their role in angiogenesis. The molecule mechanism of tsRNA-15797-modified exosomes was explored by RNA sequencing, dual-luciferase assay, and immunofluorescence. Results: A tRNA-derived small RNA tsRNA-15797 was down-regulated in plasma exosomes of ONFH patients. We found the effects of BMSCs-derived exosomes on accelerating HUVECs angiogenesis and migration, which were further enhanced after overexpressing tsRNA-15797. Besides, overexpression of tsRNA-15797 would lead to down-regulation of LFNG correlated with angiogenesis. tsRNA-15797 could directly interact with LFNG. We demonstrated that LNFG overexpression weakened the pro angiogenic and migratory effects of tsRNA-15797-modified BMSCs-derived exosomes. Conclusion: We successfully constructed tsRNA-15797-modified BMSC-derived exosomes and demonstrated that it induced the angiogenesis of HUVECs by targeting the down-regulation of LFNG. Thus, tsRNA-15797-loaded BMSCs-derived exosomes may be a potential target therapy drug for ONFH.
