Among G1 (the screening group), nonattenders had higher all-cause mortality than attenders: HR 2.01 (1.74 to 2.32) and were younger, more obese, more likely to be men, and less likely to be taking antihypertensive medications.
- ‡‡
Adjusted for age, sex, and deprivation (determined using the Townsend Index, which was calculated using postcodes to determine material deprivation based on four factors derived from the 1991 UK census: unemployment, overcrowding, car ownership, and home ownership).

For phase 1, comparing those who attended screening vs. controls (G1-a vs. G2), the HR for all-cause mortality was 0.64 (0.47 to 0.86) and the adjusted HR was 0.54 (0.40 to 0.74). Comparing those who did not attend screening vs. controls (G1-b vs. G2), the HR for all-cause mortality was 1.68 (1.27 to 2.22) and the adjusted HR was 1.36 (1.01 to 1.82). For phase 2, comparing those who attended screening vs. controls (G1-a vs. G2), the HR for all-cause mortality was 0.46 (0.31 to 0.69) and the adjusted HR was 0.52 (0.35 to 0.78). Comparing those who did not attend screening vs. controls (G1-b vs. G2), the HR for all-cause mortality was 1.85 (1.45 to 2.36) and the adjusted HR 1.73 (1.34 to 2.24).
