Explanatory models for Group B (Bangladeshi sedentee women)

Model B1: Vitamin D as a continuous variable in Bangladeshi sedentees, n = 45
Variables	B	95% CI (lower)	95% CI (upper)	P
Low ferritin statusa	0.841	−10.680	12.362	0.884
BMI	−0.319	−1.272	0.635	0.504
Age	−0.271	−0.921	0.380	0.405

Model B3: Odds ratios in sedentees of being insufficient, n = 19, versus sufficient, n = 26
Variables	OR	95% CI (lower)	95% CI (upper)	P
Low ferritin statusa	1.108	0.205	5.984	0.905
BMI	0.918	0.793	1.062	0.250
Age	1.044	0.947	1.150	0.387

Model B2 has not been included due to small sample size in the deficient group (n = 2). Adjusted R² for model B1: −0.049.
