Pressure pain detection thresholds (PPT) at the proximal tibia are predicted by ROC- and a priori- binary manikin classifications in individuals within the knee pain sample (n=322)
| n (%) | b (95% CI) | β | p | |
|---|---|---|---|---|
| ROC-Derived Classifications | ||||
| ≥5/7 other sites | 62 (19%) | -0.20 (-0.37 to -0.03) | -0.14 | 0.02 |
| ≥6/23 other sites | 86 (27%) | -0.19 (-0.34 to -0.04) | -0.14 | 0.01 |
| A priori Classifications | ||||
| Above waist | 189 (59%) | -0.08 (-0.22 to -0.06) | -0.07 | 0.26 |
| Below waist | 169 (52%) | -0.17 (-0.30 to -0.03) | -0.14 | 0.02 |
| Contralateral to index knee | 119 (37%) | -0.14 (-0.28 to 0.002) | -0.12 | 0.05 |
| Axial pain | 151 (47%) | -0.01 (-0.15 to 0.12) | -0.01 | 0.87 |
| Widespread paina | 31 (10%) | -0.08 (-0.34 to 0.18) | -0.03 | 0.55 |
Classifications are based on number or distribution of painful sites in addition to knee pain reported by participants on a body manikin. ROC; receiver-operating curve.
a
Widespread pain; classified according to American College of Rheumatology criteria37, including knee pain.
Bold indicates statistically significant associations.
Proportion (n, %) of participants with knee pain reporting other pain according to classifications are presented.
Unstandardized (b) and standardized (β) regression coefficients are presented.
