Association between sociodemographic characteristics and participation in active travel (N = 26,022). RR: Pooled risk ratio; 95%CI: 95% confidence interval; N: number of studies in two-step individual participant data meta-analysis; P-value: corresponds to the Z-test of significance for the pooled RR; I-squared: I2 statistic indicates proportion of variation due to between-study heterogeneity; P: corresponds to the P-value for the chi-squared test of heterogeneity. Pooled RRs calculated from two-step individual participant data meta-analysis of individual study RRs, estimated by multivariable mixed effects Poisson regression models with robust standard errors, adjusted for levels of clustering and all other covariates in the figure except residence location. Categorical variables for age, education and BMI were included in the model as continuous variables to reduce the degrees of freedom and enable model convergence. Residence location: N = 20,022. Men were the reference for women; public and private employees were the reference for employment; urban residents were the reference for rural residents
