"No connection could be traced between the amount of antitoxin administered and the occurrence of rashes or late pyrexia, but the pain in and about the joints appears to have a relationship to the amount of antitoxin used.
"The results of the Committee's investigation tend to show that by the use of antitoxin—
1. The general mortality is reduced by one-third.
2. The mortality in tracheotomy falls by one-half.
3. Extension of membrane to the larynx very rarely occurs after the administration of antitoxin.
4. The duration of life in the fatal cases is decidedly prolonged.
5. The number of fatal cases is less when antitoxin is used early in the illness than in those which do not receive it until a later period.
6. The frequency of the occurrence of paralysis is not diminished, but the percentage of recoveries in cases with paralysis is slightly increased.[22]
7. Rashes are produced in about one-third of the cases, and are attributable to the antitoxin.
8. Pain, and occasionally swelling about the joints, are produced in a number of cases.
