RCT with 153 patients treated with a nitric oxide nasal spray, and 153 placebo patients, showing faster viral clearance with treatment. NO generated by a nasal spray (NONS) self-administered six times daily as two sprays per nostril (0.45mL of solution/dose) for seven days.
risk of no improvement, 41.9% lower, RR 0.58, p = 0.06, treatment 14 of 64 (21.9%), control 26 of 69 (37.7%), NNT 6.3, mITT high risk, day 18.
risk of no improvement, 66.8% lower, RR 0.33, p = 0.04, treatment 4 of 64 (6.2%), control 13 of 69 (18.8%), NNT 7.9, mITT high risk, day 16.
risk of no improvement, 67.7% lower, RR 0.32, p = 0.08, treatment 3 of 64 (4.7%), control 10 of 69 (14.5%), NNT 10, mITT high risk, day 8.
risk of no improvement, 22.3% lower, RR 0.78, p = 0.63, treatment 8 of 105 (7.6%), control 10 of 102 (9.8%), NNT 46, day 18, modified intention-to-treat.
risk of no improvement, 17.8% lower, RR 0.82, p = 0.67, treatment 11 of 105 (10.5%), control 13 of 102 (12.7%), NNT 44, day 16, modified intention-to-treat.
risk of no improvement, 8.9% lower, RR 0.91, p = 0.76, treatment 30 of 105 (28.6%), control 32 of 102 (31.4%), NNT 36, day 8, modified intention-to-treat.
viral load, 19.8% lower, relative load 0.80, p < 0.001, treatment mean 2.62 (±0.145) n=64, control mean 2.1 (±0.141) n=69, mITT high risk, day 8.
viral load, 13.5% lower, relative load 0.86, p < 0.001, treatment mean 2.51 (±0.114) n=105, control mean 2.17 (±0.118) n=102, day 8, modified intention-to-treat.
time to viral-, 26.1% lower, relative time 0.74, p = 0.09, treatment 64, control 69, mITT high risk, Kaplan–Meier.
time to viral-, 6.5% lower, relative time 0.94, p = 0.66, treatment 105, control 102, Kaplan–Meier, modified intention-to-treat.
