The survivorship curve is a useful visualisation of the frequency distribution of the age classes of a population (Rauschert2010) and is calculated aslx = nx/n0, wherenxis the number of individuals in the study population who survive to the beginning of age categoryxandn0is the number of...
However, no significant difference was found in the survivorship when stratified by gender (P = 0.05), BMI ≥ 25 kg/m2 (P = 0.16), or the presence of labral tear (P = 0.33). Cox proportional hazards model showed that age ≥ 55 years (P = 0.03; hazard ratio [HR] 4.4; 95% CI ...

Fig. 1 Survivorship curve of the Ferrocalamus strictus popu- lation. 但是从3年生进入到4–5年生的机会比较少.出现此 种现象可能与铁竹的死亡原因有关. 3.2.3 铁竹种群生殖力 生殖力表(表4)分析结果显示, 铁竹种群的净增 殖率(R0)为1.10, R0 > 1, 表明铁竹种群为增长型(按 发笋率计算).内禀...
The survival rate of the high expression group of FGFR4 mRNA was lower than that of the low expression group, and the average survival time of the high expression group was shorter than that of the low expression group, and the survivorship curve of the two groups was statistically ...

ICU感染患者病死率随qSOFA评分增高而升高,不同qSOFA评分患者间病死率差异有统计学意义(χ 2=84.605, P=0.000)。根据qSOFA最佳截断值将患者分为两组,qSOFA≥2分组患者的死亡风险明显高于qSOFA<2分组〔优势比( OR)=2.767,95%可信区间(95% CI)=2.116~3.617, P=0.000〕。 结论qSOFA、SOFA和APACHEⅡ评分均...
