Hazard ratios and 95% confidence intervals for mosaic loss of the Y chromosome (mLOY) and all-cause mortality using age as the underlying time metric (N = 223, 338).

| No. deaths | 8401 | 8401 | 8401 | ||||||

| Age-adjusteda | 1.37 | (1.23–1.53) | 1.7 × 10−8 | 1.88 | (1.50–2.36) | 6.0 × 10−8 | 1.06 | (1.04–1.08) | 9.0 × 10−12 |
| Age- & smoking-adjustedb | 1.06 | (0.95–1.18) | 0.31 | 1.35 | (1.08–1.70) | 0.01 | 1.01 | (0.99–1.03) | 0.24 |

aAdjusted for age using age as the underlying time metric in the Cox proportional hazards regression model.
bAdditionally adjusted for detailed smoking history (25-level variable incorporating current smoking status, smoking intensity (current and former smokers); time since quitting (former smokers), and cigar and pipe use (current and former smokers).
cAdditionally adjusted for race/ethnicity (white, black, Asian, mixed, or other race); alcohol drinking (never drinker, former drinker, infrequent drinker (<1 drink/week), occasional drinker (>1 drink/week but <1 drink/day), moderate daily drinker (1 to 3 drinks/day), or heavy daily drinker (>3 drinks/day)); general health status (excellent, good, fair, or poor); education level (college or university degree, A levels/AS levels or equivalent, O levels/GCSEs or equivalent, CSEs or equivalent, NVQ or HND or HNC equivalent, or other professional qualifications); body mass index (<18.5, 18.5 to <25, 25 to <30, 30 to <35, or ≥35 kg/m2); and physical activity (>10 minutes of moderate of vigorous activity 0, 1-2, 3-4, or ≥5 days/week).
dScaled by the - (standard deviation) of mLRR such that the HR corresponds to a one standard deviation decrease in mLRR. Abbreviations: CI, confidence interval; HR, hazard ratio; mLOY, mosaic loss of the Y chromosome; mLRR, median log2 intensity ratio of the Y chromosome.
