a, Standardised Mean Difference between age at diagnosis before vs. during lockdown, >.1. b, Standardised Mean Difference between age at diagnosis before vs. after lockdown, >.1. c, proportions rounded to nearest 1% in order for frequencies <5 to remain masked. Cancer cohorts defined as first ever, incident cancer (excluding same cancer any time in history).
