Table 2 SIR and SMR for Rhodes study area compared with New South Wales and compared with Ryde and Concord SLAs for all cancers.

From: Effect of a chemical manufacturing plant on community cancer rates

Time Frame Number of cases/ deaths Comparison Area Case SIR (Indirectly Standardised) 95% Confidence Interval Death SMR (Indirectly Standardised) 95% Confidence Interval
30 years 1106/524 New South Wales 87.6# (82.5, 92. 9) 88.7# (81.3, 96.7)
30 years 1106/524 Concord and Ryde SLAs 90.5# (85.2, 96.0) 92.9 (85.1, 101.2)
25 years 922/530 New South Wales 91.2# (85.4, 97.2) 93.5 (85.2, 102.3)
  1. Notes:
  2. SLA = Statistical Local Area
  3. SIR = Standardised Incidence Ratio
  4. SMR = Standardised Mortality Ratio
  5. # Statistically significantly lower than the comparison area
  6. * Statistically significantly higher than the comparison area
