Probiotics use is associated with improved clinical outcomes among hospitalized patients with COVID-19
Retrospective 375 patients in China, 179 treated with probiotics (Bifidobacterium, Lactobacillus, and Enterococcus), showing improved clinical outcomes with treatment.
Zhang et al., 8/4/2021, retrospective, China, Asia, peer-reviewed, 14 authors.
hospitalization time, 13.6% lower, relative time 0.86, p = 0.009, treatment 150, control 150, PSM.
time to clinical improvement, 14.3% lower, relative time 0.86, p = 0.02, treatment 150, control 150, PSM.
time to viral-, 16.7% lower, relative time 0.83, p < 0.001, treatment 150, control 150, PSM.
Effect extraction follows
pre-specified rules
prioritizing more serious outcomes. For an individual study the most serious
outcome may have a smaller number of events and lower statistical signficance,
however this provides the strongest evidence for the most serious outcomes
when combining the results of many trials.
