| Outcomes | WA1 | WA2 | WA3 | WA4 | WA5 | WA1-5 | PGAP |
|---|---|---|---|---|---|---|---|
| Number | 53 | 53 | 53 | 53 | 53 | 53 | 53 |
| Median | 2 | 3 | 0 | 1 | 2 | 1.6 | 3 |
| Mean | 2.45 | 0.59 | 1.36 | 1.81 | 1.83 | ||
| SD | 1.62 | 1.50 | 1.24 | 1.48 | 1.61 | 1.05 | 1.51 |
WA1 to WA5 = Items 1 to 5 of WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) pain subscore on a 11-point rating numeric scale (0-10); WA1-5 = WOMAC pain subscore normalized on a 11-point rating numeric scale (0-10); PGAP = Patient global assessment of pain on a 11-point rating numeric scale (0-10).
In paired Student t test WA2 and PGAP were significantly higher than other outcomes measures (all P values <0.001) and were not statistically different between themselves (P > 0.05).
