Erratum: The effect of educational intervention based on the health belief model on osteoarthritis-preventive behaviors in middle-aged women

In the article titled “The effect of educational intervention based on the health belief model on osteoarthritis-preventive behaviors in middle-aged women”, published on pages 327, Issue 1, Volume 9 of Journal of Education and Health Promotion,[1] [Tables 2 and 3] has been incorrectly published. The table legend and table number are correct. The correct Table 2 and 3 is mentioned below:
