In this population-based study, they concluded that TB survivors with both a medical history and TB scars on CXR had an increased risk of sarcopenia (odds ratio [OR] 3.44, 95% confidence interval [CI] 1.79–6.68) and osteoporosis (OR 1.75, 95% CI 1.04–2.95) after adjusting for age, height, alcohol, smoking, physical activity, parathyroid hormone level, serum 25-hydroxyvitamin D, education, and fat mass index [41]. Here, PTH is linked to osteoporosis.
