Incorrect Units: In the Original Contribution
entitled "Effect of Magnetic vs Sham-Magnetic Insoles on Plantar Heel Pain:
a Randomized Controlled Trial" published in the September 17, 2003, issue
of THE JOURNAL (2003;290:1474-1478), some data were reported with incorrect
units. In Table 1, the mean (SD) duration of pain should have been reported,
not in months, but in weeks (ie, 120  weeks in the nonmagnetic insole
group and 85  weeks in the magnetic insole group).
