Multivitamin usage prior to diagnosis was found to reduce the symptoms of chemotherapy induced peripheral neuropathy.
Yet the conclusion of the authors were as follows:
Multivitamin use may be associated with reduced risk of CIPN, although individual dietary supplement use did not appreciably affect risk. Multivitamin use could be a surrogate for other related behaviors that are the actual drivers of the association with reduced CIPN. Without prospective randomized trials of vitamin supplementation, recommendations for use or changes to clinical practice are clearly not warranted.
What they were trying to say is, maybe there are something else that these patients have that might reduce the side effects? well obviously its the multivitamins making them healthier…
