Another meta-analysis, published in 2013, found that multivitamin-multimineral treatment "has no effect on mortality risk," and a 2013 systematic review found that multivitamin supplementation did not increase mortality and might slightly decrease it. A 2014 meta-analysis reported that there was "sufficient evidence to support the role of dietary multivitamin/mineral supplements for the decreasing the risk of age-related cataracts." A 2015 meta-analysis argued that the positive result regarding the effect of vitamins on cancer incidence found in Physicians' Health Study II (discussed above) should not be overlooked despite the neutral results found in other studies.
