Task: Answer Verification
Input (English): Question: Is transdermal posterior tibial nerve laser therapy effective in women with interstitial cystitis?
Answer: This study demonstrated no difference between the active and sham device. However, it is interesting that treatment and control cohorts experienced similar improvements, suggesting that the control cohort improvements may have been due to participants' belief that they were receiving active treatment from the stimulator. These findings provide support for investigating placebo effects in randomized trials.
Output (English): no
