Hazard ratios were assessed using Cox-regression for all-cause mortality and competing risks regression for cause-specific mortality.
1p-value for test of HTLV-1 pVL trend across the 3 categories conducted using the median pVL value for each category.
2Adjusting for alcohol, place of adult residence (Alice Springs, Remote, Town camp or other States), age at test and gender. All other causes of death were treated as a competing risk.
