  1. Data are expected QALY (95% credibility interval) and expected costs (95% credibility interval) per 1,000 households. (1) UC = usual care; (2) E = education; (3) E + FE = education plus low cost/free safety equipment; (4) E + FE + HI = education plus low cost/free safety equipment plus home inspection; (5) E + FE + F = education plus low cost/free safety equipment plus fitting; (6) E + HI = education plus home inspection; (7) E + FE + F + HI = education plus low cost/free safety equipment plus fitting plus home inspection. Probability CE = probability that intervention is cost effective at a £30,000/£50,000 threshold value. QALYs = quality-adjusted life years.
