In a study that also compared the predictive value of ratio indicators, it draws the conclusion that platelet-to-lymphocyte, neutrophil-to-lymphocyte, lymphocyte-to-monocyte ratio, and aspartate-to-alanine aminotransferase ratios are inexpensive, easy, fast, and reproducible parameters that can be used in determining the prediction of carotid artery stenosis (Han et al., 2021). The gene discussed is GPT; the disease is coronary atherosclerosis measurement.
