In the Preliminary Communication entitled
"Percutaneous Electrical Nerve Stimulation for Low Back Pain: A
Randomized Crossover Study," published in the March 3, 1999, issue of
THE JOURNAL (1999;281:818-823), a potential
financial conflict was not revealed. One month after submission of
their manuscript to JAMA, Drs White and Craig incorporated a
company named PENS Inc to produce a Food and Drug
Administration–approvable stimulating unit to provide percutaneous
electrical nerve stimulation (PENS) therapy. Drs White and Craig
completed their financial disclosure statements at the time of
submission but these disclosure statements were not updated after the
company was incorporated.
Also, on page 819, under the heading
"Methods," "mean ± SD age, 43 ± 1.9 years, and weight, 66 ±
1.6 kg" should have read 43 ± 19 years and 66 ± 16 kg.
