 Postoperative average distance of 6MWT at 10weeks postsurgery can be calculated using the following equations where males are coded “0” and females are “1”
 Males: 490 + (1 × 73.8) + (1x 20.5) + (0 × 62.4) + (66.2 × −2.9), where 66.2 is the average age
 Females: 490.0 + (1 × 73.8) + (1x 20.5) + (1 × 62.4) + (66.8x 2.9), where 66.8 is the average age
