“Once the numerator (number of adverse events) and denominator (number of treatments) are known, potential adverse events with chiropractic can be put into context, relative to risks associated with other therapies, such as adverse events due to medications or surgery. The risk:benefit ratio can only be considered if data on both efficacy and harm are collected; at present, in children, neither is substantive. Ultimately, these data are needed so that paediatric patients, their families and their healthcare providers can better evaluate ‘what’s the harm’ with respect to children and chiropractic.” Sunita Vohra MD, Focus on Alternative and Complementary Therapies [FACT] (March 2004)
