  Figure 2.. Adjusted odds ratios for AAC prevalence by muscle strength in male participants. Each odds ratio was calculated using a muscle strength of 85.5 kg as the reference. The odds ratio was adjusted for age, alkaline phosphatase, body mass index, diabetes, drinking status, education level, fasting plasma glucose, hyperlipidemia, hypertension, low-density lipoprotein cholesterol, poverty–income ratio, race, serum calcium, serum creatinine, serum phosphate, smoking status, systolic blood pressure, and triglyceride. The red solid line represents the odds ratio across the whole range of muscle strength. The red dotted line represents the 95% CI. The black dotted line indicates the reference line (HR = 1). Histograms show the frequency distribution of muscle strength. AAC: abdominal aorta calcification; CI: confidence interval; HR: hazard ratio.

  Figure 3.. Adjusted odds ratios of AAC prevalence by muscle strength in female participants. Each odds ratio was calculated using a muscle strength of 55.5 kg as the reference. The odds ratio was adjusted for age, alkaline phosphatase, body mass index, diabetes, drinking status, education level, fasting plasma glucose, hyperlipidemia, hypertension, low-density lipoprotein cholesterol, poverty–income ratio, race, serum calcium, serum creatinine, serum phosphate, smoking status, systolic blood pressure, and triglyceride. The red solid line represents the odds ratio across the full range of muscle strength. The red dotted line represents the 95% CI. The black dotted line indicates the reference line (HR = 1). Histograms show the frequency distribution of muscle strength. AAC: abdominal aorta calcification; CI: confidence interval; HR: hazard ratio.

  Figure 4.. Subgroup analysis of the association between muscle strength and AAC prevalence in male participants. Logistic regression was performed after adjustment for age, alkaline phosphatase, body mass index, diabetes, drinking status, education level, fasting plasma glucose, hyperlipidemia, hypertension, low-density lipoprotein cholesterol, poverty–income ratio, race, serum calcium, serum creatinine, serum phosphate, smoking status, systolic blood pressure, and triglyceride. AAC: abdominal aorta calcification.

Logistic regression was performed after adjustment for age, alkaline phosphatase, body mass index, diabetes, drinking status, education level, fasting plasma glucose, hyperlipidemia, hypertension, low-density lipoprotein cholesterol, poverty–income ratio, race, serum calcium, serum creatinine, serum phosphate, smoking status, systolic blood pressure, and triglyceride. AAC: abdominal aorta calcification.
