The Geography of Primary Hepatic Neoplasms Treatments in Canada: Changes in Latitudes and Changes in Attitudes

Figure 1

Standardized Incidence Ratio (SRI) and respective 95% confidence limits for ablation (a), hepatic resection (b), liver transplantation (c), and transarterial locoregional therapies (d) for the treatment of primary hepatic liver tumors in Canada during the period between 2002 and 2013. Values of SRI equal to 1.0 indicated that the treatment modality in the region was equal to the expected countrywide average adjusted for age and gender of the population. SIR values more or less than 1.0 indicated that the treatment modality was above or below the expected countrywide average adjusted for age and gender. Statistically significant differences were identified when 95% confidence intervals of SIR did not include the value of 1.0 ( value ≤ 0.05).
