Interaction terms for all-cause mortality modela
| Variable | Comparison used in rate ratio | Rate ratio (other death/HIV/TB death) | 95% Confidence interval (p value) |
|---|---|---|---|
| Sex | Male/female | 1.12 | 0.99–1.27 (0.077) |
| Country of origin | South Africa/Mozambique | 0.85 | 0.75–0.98 (0.023) |
| Residence status | Temporary/permanent | 1.05 | 0.91–1.21 (0.493) |
| Distance from Bhubezi(km) | Greater than 5 km/5 km or less | 1.02 | 0.86–1.20 (0.842) |
| SEP quintiles | Quintiles 2–5/quintile 1 | 0.95 | 0.81–1.11 (0.503) |
| Mean level of household education | Greater than 7 years/7 years or less | 0.93 | 0.82–1.06 (0.294) |

Values derived from a multivariate Poisson model for all-cause mortality for deaths of known cause. The model included all terms significant at the 10% level in the bivariate model. Individual interaction terms between cause of death (HIV/TB or Other) and individual terms were introduced individually in a series of models. Results shown are for models for which convergence was achieved.
