Prophylaxis RCT with 394 healthcare workers, 196 treated with iota-carrageenan, showing significantly lower symptomatic cases with treatment. There were no deaths or hospitalizations. There was a significant number of PCR- symptomatic cases (7.6% treatment and 8.6% control). The two treatment cases occurred shortly after randomization - infection may have occurred before the start of treatment. CARR-COV-02. NCT04521322.
risk of symptomatic case, 80.2% lower, RR 0.20, p = 0.03, treatment 2 of 196 (1.0%), control 10 of 198 (5.1%), NNT 25, odds ratio converted to relative risk.
Effect extraction follows pre-specified rules prioritizing more serious outcomes.
