BMI: body mass index (18–25 kg/m2); WBC: white blood cells (4.5–11.0 ×1000/μL); Hb: hemoglobin (12.0–16.0 g/dL); PLT: platelets (130–400 ×1000/μL); Vit.D: vitamin D (sufficient >30 ng/mL), Ca: calcium (2.12–2.52 mmol/L); Phos: phosphorus (0.81–1.58 mmol/L); ALP: alkaline phosphatase (50–136 U/L); ESR: erythrocyte sedimentation rate (0–20 mm/hr); DAS28-ESR: disease activity score in 28 joints using erythrocyte sedimentation rate.
value was determined according to ANOVA test.
Letters with different superscripts in the same row are significantly () different according to post hoc LSD test.
