Derivation of a clinical prediction rule to determine fall risk in community-dwelling individuals with knee osteoarthritis: a cross-sectional study

Summary We derived a clinical prediction rule (CPR) to determine fall risk. The probability of falls increased, with positive likelihood ratio being 17.8 and post-test probability (positive predictive value) being 88.2%, in cases where the CPR score was 2 points. Our CPR could be a useful screening test to detect fall risk probability.
