This report describes a randomized double-blind placebo-controlled trial on vitamin C supplementation against the common cold. This is not available through the web, and is therefore made available here. "There was no consistent difference between groups in the incidence of runny nose or sneezing. Man days of morbidity for hoarseness, sore throats, non-productive coughs, and productive coughs was 36, 107, 42 and 72 in the placebo group with only 37%, 28%, 40% and 31% as much morbidity in the AA group. The Wilcoxon Sequence Test with a one tailed test rejected the null hypothesis of equal effectiveness of the AA and placebo for sore throats and productive coughs (P = .0155 and .0327) but not for hoarseness or non-productive coughs."
