Table 3 Adjusted Odds Ratios and 95% Confidence Limits for Levels of Walk to School (WTS) Program Implementation, US Walk to School Evaluation Project, 2002^a

Label	Estimate (SE)	Odds Ratio ^c	95% Confidence Limits
Funding: Both Logits^b	0.44 (0.11)	1.56	1.26, 1.92
Years of Participation: Both Logits	0.37 (0.08)	1.44	1.23, 1.70
Number of Groups Involved:
(low vs. medium or high)	0.57 (0.11)	1.78	1.44, 2.18
(low or medium vs. high)	0.44 (0.13)	1.56	1.22, 1.99
Use of a Walkability Assessment:
(low vs. medium or high)	0.78 (0.22)	2.17	1.42, 3.32
(low or medium vs. high)	1.17 (0.29)	3.22	1.84, 5.64

a: Levels were defined as follows: low (participated in WTS Day only), medium (participated in promotions in addition to WTS Day), and high (made policy or environmental changes to support walking to school).
b: The proportional odds model provides 2 response category comparisons: (1) school level low vs. medium and high collectively, and (2) levels low and medium vs. high.
c: Analyses were performed with control for the other 3 variables.
