Model 2 - Hierarchical logistic regression analysis of Persistent Post-surgical Pain 4–6 months (T3) following TKA and THA on demographic and clinical baseline measures (T1), and post-surgical pain and anxiety 48 h after surgery (T2).
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Note. After removing 2 outliers, this final model correctly predicted 75% of all patients; χ2(5) = 27.935 p<0.001; Nagelkerke R2 = 0.372; OR = odds ratio; CI = confidence interval; bold = significant at p≤.05.1
Continuous variable, NRS - Numerical Rating Scale (0–10) from BPI-SF: Brief Pain Inventory-Short Form;2
Dichotomic variable: 0 = THA: Total Hip Arthroplasty; 1 = TKA: Total Knee Arthroplasty;a
Continuous variable, HADS-A: Hospital Anxiety and Depression Scale - anxiety subscale.
