Comparison with first round findings of faecal haemoglobin concentrations and clinical outcomes in the second round of a biennial faecal immunochemical test based colorectal cancer screening programme.

J Med Screen 2022 Jun 23:9691413221110012. Epub 2022 Jun 23.

Centre for Research into Cancer Prevention and Screening, University of Dundee, UK.
