PVP-I for COVID-19
13th treatment shown to reduce risk in February 2021
 
*, now known with p = 0.000000037 from 20 studies.
Lower risk for mortality, cases, and viral clearance.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
3,800+ studies for 60+ treatments. c19early.org
Tiny RCT with 5 PVP-I patients, 6 saline patients, and 8 control patients, showing improved viral clearance with 0.23% povidone-iodine (PVP-I) nasal rinses and mouthwashes. No significant differences were found for viral load by PCR cycle threshold values or patient-reported symptom scales.
Authors claim the trial is placebo controlled, however they state that the control group "did not receive any intervention".
WURSS-11 was higher in the PVP-I group vs. control at baseline (29 vs. 24).
Authors report that patients developed symptoms within the last three days, however the mean baseline Ct for the PVP-I group was 23, indicating high viral load and suggesting later treatment.
Figure 1 shows patients lost to followup in both the PVP-I and NS groups. For PVP-I, Figure 2 indicates a patient censored at day 4 and only 4 patients with further data, but Table 2 shows a mean viral clearance of 9.8 days from 5 patients.
risk of no recovery, 16.4% lower, RR 0.84, p = 0.76, treatment mean 4.6 (±4.0) n=4, control mean 5.5 (±5.0) n=8, mid-recovery, day 4.

relative improvement in viral load, 72.7% better, RR 0.27, p = 0.72, treatment mean 2.2 (±4.88) n=5, control mean 0.6 (±8.7) n=8, day 4.
time to viral-, 22.2% lower, relative time 0.78, p = 0.02, treatment mean 9.8 (±1.6) n=4, control mean 12.6 (±1.68) n=8.
