Table 2. Association between county characteristics and the probability of having an existing heat plan in 2011, based on a simple logistic regression of heat plan status on each community characteristic.
County characteristic (n = 185) Percentile Expected percent of heat plan at OR (95% CI)
25th 75th 25th percentile 75th percentile
The ORs and 95% CIs are shown for a change covering the interquartile range across all counties for each county ­characteristic.
