Standardized Relative Risks of hospitalization for injury due to unintentional fall, British Columbia, 1991–2010.

Notes:
* probability (2-sided, z-test) that Ln((SRR 2010)/(SRR 1991)) Aboriginal = Ln((SRR 2010)/(SRR 1991)) BC
SRR: Standardized Relative Risk (indirectly standardized by age, gender and HSDA, compared to the total population of BC, 1991 to 2010) = Observed/Expected
L95CL: lower limit of the 95% confidence interval for the annualized % change.
U95CL: upper limit of the 95% confidence interval for the annualized % change.

备注：
* 双侧z检验对应的显著性概率，用于检验「Ln((SRR 2010)/(SRR 1991)) 原住民群体」与「Ln((SRR 2010)/(SRR 1991)) 不列颠哥伦比亚省（BC）全体人群」是否相等。
标准化相对风险（Standardized Relative Risk，SRR）：以1991至2010年不列颠哥伦比亚省总人口为参照，按年龄、性别及健康服务交付区域（Health Service Delivery Area，HSDA）进行间接标准化，计算公式为观测值/预期值（Observed/Expected）。
L95CL：年度百分比变化的95%置信区间下限。
U95CL：年度百分比变化的95%置信区间上限。
