Note. BIXI = BIcycle-taXI; CI = confidence interval; OR = odds ratio. With control for built environment and sociodemographic characteristics.
Models control for mean weekly temperature, days of precipitation, density of destinations, street connectivity, age, gender, education, employment, body mass index (weight in kilograms divided by the square of height in meters), and self-rated health. Number (%) of cyclists for each analysis, 10 min: 771 (12); 30 min: 704 (11); 45 min: 617 (9.6).
