Correction

In the article “Arthritis, osteoporosis, and low back pain. Evidence-based clinical risk assessment for physical activity and exercise clearance,”¹ references 25 and 26 should have been replaced, and in “Prediabetes and type 2 diabetes mellitus. Assessing risks for physical activity clearance and prescription,”² references 8 and 9 should have been replaced, in both cases with the following reference:

Warburton DER, Jamnik VK, Bredin SSD, Gledhill N. The Physical Activity Readiness Questionnaire (PARQ+) and electronic Physical Activity Readiness Medical Examination (ePARmed-X+). Health Fitness J Can 2011;4(2):3–23.

The authors apologize for this error and any confusion it might have caused.
