Chapter 4 84 places (95%CI: 53-79; 5 estimates; 5,549 observations). For outdoor hospitality places pooled support was 50% (95%CI: 43-56; 24 estimates; 114,062 observations) and lowest pooled support was found for outdoor private places with 41% (95%CI: 18-69; 3 estimates; 10,862 observations). Figure 2: Summary of pooled support estimates for six categories of smoke-free places, and 15 subcategories. Pooled support was obtained from three-level random effect meta-analysis. *Each estimate represents a separate meta-analysis Support was highest for policies making cars carrying children smoke-free (86%, 95%CI: 81-89; 30 estimates; 518,621 observations), followed by playgrounds (80%, 95%CI: 72-86; 21 estimates; 249,127 observations) and school grounds (76%, 95%CI: 69-83; 23 estimates; 104,307 observations). For all subcategories except outdoor private areas, we found a mean pooled support higher than 50%. Places with relatively low levels of support included: parks and beaches (53%, 95%CI: 47-59; 3- estimates; 143,599 observations), outdoor hospitality places (50%, 95%CI: 43-56; 24 estimates; 114,062 observations) and outdoor private places (41%, 95%CI: 18-69; 3 estimates; 10,862 observations).
