  1. *There were 88 (4.4 %) cases in AGSN and 219 (4.4 %) outside of AGSN where the case’s DOT status was unknown
  2. §Relative risk (RR) estimating crude risk of outcome in patients undergoing DOT compared to patients not undergoing DOT in slum versus non-slum neighborhood
  3. P-values assessing for effect measure modification of AGSN census tracts on the relationship between DOT and respective outcome with the Mantel-Haenszel chi-square test
