Xn 9000 automated hematology analyzer

The covariates measured in this study were age (years), sex (male vs. female), body mass index (BMI), income (Korean won per month), marriage (married with a spouse vs. married without a spouse vs. never married), education (elementary or less vs. middle or high school vs. college or higher), heavy alcohol consumption, smoking status, multimorbidity, and hemoglobin [25 (link),26 (link)]. Covariates were assessed using a self-reported questionnaire [26 (link)]. Past (at least 100 cigarettes in their lifetime) and current smokers were categorized as smokers, and the others were categorized as non-smokers. Heavy alcohol drinkers were defined as those who consumed > 14 drinks per week for males and >7 drinks per week for females [27 (link)]. Multimorbidity was defined as being diagnosed with two or more chronic conditions [28 (link)]. Serum hemoglobin was measured based on the SLS hemoglobin detection method with a Sysmex XN-9000 Automated Hematology Analyzer (Sysmex Corporation, Kobe, Japan).

Serum hemoglobin was measured based on the SLS hemoglobin detection method with a Sysmex XN-9000 Automated Hematology Analyzer (Sysmex Corporation, Kobe, Japan), which uses cyanide-free sodium lauryl sulfate (SLS). Anemia was defined according to the WHO criteria of serum hemoglobin concentrations of less than 13.0 g/dL for men, less than 12.0 g/dL for non-pregnant women, and less than 11.0 g/dL for pregnant women [25 ].
