Table 1
Smallest detectable difference (SDD) of the 0–100 mm pain VAS reported in studies of rheumatoid arthritis.

SD: standard deviation; SDD: smallest detectable difference; VAS: visual analog scale. a0–100 mm pain VAS from 0, no pain, to 100, very severe pain. bAll 10-mm scale values were converted to a 100-point scale by multiplying by ten. cValues provided by T. Pincus and C. Swearingen for the “line 1” scores (see original article). |
