1) The effect of 1 g daily doses of L-ascorbic acid in reducing the incidence of the common cold in a group of volunteers was compared with a control group receiving a placebo, The survey lasted 16 weeks during the winter months of 1971/1972. The results (1) showed that the 47 volunteers receiving L-ascorbic acid suffered a total of 44 colds, whereas the 43 people taking dummy pills had 80 colds, That is, 1 g L-ascorbic acid/day reduced the incidence of cold symptoms by 49%.

TL;DR: Using data from the same studies, it is calculated that vitamin C (1-6 g/day) decreased the duration of the cold episodes by 0.93 +/- 0.22 (SE) days; the relative decrease in the episode duration was 21%.
