Mean Change in Weight Trajectory from Pre- to Post-Initiation

Number of post-initiation contacts per veteran	n	Mean (95% CI)*
1	93,200	−1.76 (−1.96 to −1.55)
2–5	73,612	−2.04 (−2.23 to −1.85)
6–9	32,897	−3.32 (−3.70 to −2.93)
10–13	17,988	−4.85 (−5.20 to −4.49)
14–17	7424	−6.45 (−7.00 to −5.90)
18 or more	12,456	−7.10 (−7.56 to −6.64)

* The unit for weight trajectory was estimated in % body weight change per year, such that a change from pre- to post-initiation is shown as the absolute difference in % body weight change per year
