Calculates the ORAI score to identify postmenopausal women at increased risk for osteoporosis who should be selected for Bone Mineral Density (BMD) testing. The score assigns points based on age, weight, and current estrogen use.

Usage

orai_osteoporosis_score(age, weight_kg, no_estrogen_therapy)

Arguments

age	Numeric. Patient age in years. >=75: 15 pts. 65-74: 9 pts. 55-64: 5 pts. <55: 0 pts.
weight_kg	Numeric. Patient weight in kilograms. <60 kg: 9 pts. 60-69 kg: 3 pts. >=70 kg: 0 pts.
no_estrogen_therapy	Numeric (0 or 1). Is the patient NOT currently taking estrogen? (1 = Yes/No Estrogen, +2 pts).

Recommendation	Guidance regarding BMD testing.
