Table A2. aRRsa and 95% CrIsb of method-specific suicide ratesc associated with one SD increase in levels of each of the three means accessibility indicators across 432 neighborhoods in Taipei City, 2004–2010: sensitivity analyses (A) using gamma distribution (0.01, 0.01) priors for the inverse of the variance of the unstructured and structured variability in the Bayesian hierarchical model and (B) using the distance from neighborhood centroids to the nearest river as the accessibility indicator for drowning.

| Note. aRR = adjusted rate ratio; CrI = credible interval; RR = rate ratio. aAdjusted for the proportion of divorced/separated adults and median household income. b95% CrIs of RRs that do not include one are highlighted in bold. cIncluding deaths certified either as suicide, undetermined death, or injury due to suffocation or pesticide poisoning. dThese variables were first log-transformed because of their skewed distributions. | ||||||||||||
