This table presents summarised demographics, exposures and outcomes for the cohort (N=14874). Note that for age, inter-quartile range (IQR) is reported rather than full range reported to avoid potentially identifiable data as per ONS SRS requirements. For gender, the ‘Other’ category (containing a very small number of participants) has been combined with ‘Female’, again to avoid potentially identifiable data.
*
For time-to-event outcomes, the time of exposure was taken as date of the relevant NCAP audit period for each individual (1st April 2019 or 1st April 2020).
