Concentrations of iron in groundwater and HCC mortality and incidence ASRs by land subsidence levels1
Serious land subsidence No serious land subsidence P-value
Iron (mg/l) 1.04 ± 0.20 0.34 ± 0.05 < 0.001
HCC Mortality ASRs Male 61.35 ± 3.13 37.78 ± 1.05 < 0.001
Female 16.86 ± 1.81 11.26 ± 0.37 < 0.001
HCC Incidence ASRs Male 62.11 ± 5.18 34.46 ± 1.29 < 0.001
Female 15.24 ± 1.67 11.01 ± 0.57 < 0.001

1Township-specific concentrations of iron in groundwater are average values of daily measured in 1989; Township-specific HCC incidence and mortality ASRs during 1992–2001 are direct age-adjusted rates by 1979 WHO.
