求翻译：最新研究认为CHA2DS2-VASc评分较CHADS2评分更为完善，对NVAF患者卒中风险有更好的预测作用，但目前国内外有关其在NVAF缺血性脑卒中患者中的临床应用的资料较少。是什么意思？

The latest studies suggest that the the the cha2ds2-vasc score chads2 score is more perfect, the nvaf risk of stroke in patients with a better prediction, but at home and abroad, less information about its clinical application in the nvaf patients with ischemic stroke.

The most recent studies suggest that 2 CHA DS VASc score 2 - 2 score more CHADS full NVAF stroke risk patients have a better forecast, but at home and abroad for its NVAF ischemic brain stroke patients in the clinical application of the information.

The newest research thought the CHA2DS2-VASc grading compares the CHADS2 grading to be more perfect, has the better forecast function to the NVAF patient apoplexy risk, but at present domestic and foreign concerns it to be few in the NVAF anemic apoplexy patient's clinical practice material.

Latest studies suggest CHA2DS2-VASc scoring a CHADS2 score better, better prediction of stroke risk in patients with NVAF, but at home and abroad about the NVAF in ischemic stroke patients: a clinical application of less material.
