This research looked at data collected between 1999 and 2020 from the National Health and Nutrition Examination Survey. The team examined 43,321 participants, including 1,583 people with a diagnosed stroke and a matched group without stroke. They focused on the monocyte-to-high-density lipoprotein cholesterol ratio, known as MHR, which compares certain white blood cells to good cholesterol.
The study found that people with elevated MHR had a statistically significant association with a higher risk of stroke. The analysis showed an odds ratio of 1.517, meaning the risk was higher in this group. Subgroup checks confirmed that this link held true across different ages and health backgrounds.
No safety issues were reported because the study looked at existing health records rather than testing a new drug. The main caution is that this study design cannot prove that the ratio causes strokes. Readers should understand that more research is needed to confirm this link over time and to see if it can help doctors treat patients.
