Human development index is associated with mortality-to-incidence ratios of gastrointestinal cancers

Figure 1 Association between the mortality-to-incidence ratio and human development at the regional level. A: Regional age-standardized mortality (grey) and incidence (white and grey) rates per 100000 individuals for gastrointestinal cancers. The mortality-to-incidence ratios (MIRs) are denoted; B: The regional MIRs of gastrointestinal cancers overall and stomach, liver and colorectal cancers correlate with the human development index (HDI). Best-fit lines by linear regression (solid) are indicated.
