Improvement in Health-Related Quality of Life and Satisfaction after Hip Replacement: A Comparison Between Patients with Mild to Moderate and Severe Radiographical Pre-Operative Osteoarthritis.

Odds Ratios >1 indicate a higher probability of achieving a Minimal Clinically Important Difference in HRQoL after THR in patients with Kellgren Grade 3+4, compared to Grade 0–2.
The odds ratios adjusted for age, sex, Charnley Comorbidity Classification and BMI and stratified for quartiles of follow-up.

优势比（Odds Ratios）>1 提示，相较于Kellgren分级0~2级的患者，Kellgren分级3+4级的患者在接受全髋关节置换术（Total Hip Replacement，THR）后，达成健康相关生活质量（Health-Related Quality of Life，HRQoL）最小临床重要差异（Minimal Clinically Important Difference，MCID）的概率更高。本次分析的优势比已校正年龄、性别、查恩利合并症分类（Charnley Comorbidity Classification）及体重指数（Body Mass Index，BMI），并按随访四分位数进行分层。
