Uh this seems like garbage. Gargling with water helps, but gargling with an antiseptic solution makes no difference. Self reported. Gargle if it helps you feel better.

Incidence rate ratio of 0.64 (suspiciously with an upper bound of the confidence interval just under 1) strikes me as an implausibly big effect.  It implies that 36% of infections occur through a mechanism that you can block by gargling.  So, I agree with your assessment.
