Subgroup analyses of the proportion of ice cleat users among unexposed and exposed respondents and the adjusted association between ice cleat distribution programmes and self-reported ice cleat use based on linear probability models

| Secondary education or lower | 0.509 | 0.624 | 0.076 (0.042 to 0.109) | 41 044 |
| Place of birth | ||||
| Sweden | 0.534 | 0.633 | 0.069 (0.034 to 0.104) | 54 582 |
| Other | 0.417 | 0.597 | 0.109 (0.035 to 0.184) | 8652 |
Notes: Analyses were adjusted for place of birth (native, non-native), educational attainment (postsecondary education, no postsecondary education), sex, age (in 5-year age groups, except 18–24 years), survey and municipality fixed effects. Cluster-robust 95% CI (clustered by municipality) are presented in parentheses. The subgroups were modeled separately.
