18th treatment shown to reduce risk in March 2021
 
*, now known with p = 0.0000013 from 26 studies.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.

RCT with 24 probiotics and 15 control patients in Spain, showing lower overall symptoms and lower digestive symptoms with treatment. Kluyveromyces marxianus B0399 plus lactobacillus rhamnosus CECT 30579.
The immune effects of probiotics are strain-specific.
risk of no recovery, 32.7% lower, RR 0.67, p = 0.08, treatment 14 of 24 (58.3%), control 13 of 15 (86.7%), NNT 3.5, day 30.
risk of no recovery, 53.1% lower, RR 0.47, p = 0.10, treatment 6 of 24 (25.0%), control 8 of 15 (53.3%), NNT 3.5, digestive symptoms, day 30.
relative recovery, 20.0% better, RR 0.80, p = 0.03, treatment 24, control 15, relative symptom improvement, day 30.
relative recovery, 26.1% better, RR 0.74, p = 0.06, treatment 24, control 15, relative improvement for digestive symptoms, day 30.

Conflict of Interest A conflicting interest exists when professional judgment concerning a primary interest (such as patient' s welfare or the validity of research) may be influenced by a secondary interest (such as financial gain or personal rivalry). It may arise for the authors when they have financial interest that may influence their interpretation of their results or those of others. Examples of potential conflicts of interest include employment, consultancies , stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. If there are no interests to declare then please state this: ' The authors declare that there are no conflicts of interest.' Please state any competing interests: Ethical approval and informed consent (if applicable) If the work involves the use of human subjects, the author should ensure that the work described has been carried out in accordance with The Code of Ethics of the World Medical Association..
