The simple Cox Proportional Hazard Model used to estimate the unadjusted association between contraception discontinuation and injection administrator (self vs. provider) is as follows: ln(hazard of discontinuation at time t) = ln(lambda_o_hat (t)) + -0.62×1 where x1=1 for those who self-inject the contraceptive and 0 for those who have a provider inject the contraceptive. The standard error of the slope for x1 = 0.09. Is the relationship between contraception discontinuation and self-injection (compared to provider injection) statistically significant?
