Aspirin Use Is Associated With Decreased Mechanical Ventilation, Intensive Care Unit Admission, and In-Hospital Mortality in Hospitalized Patients With Coronavirus Disease 2019
Retrospective 412 hospitalized patients, 98 treated with aspirin, showing lower mortality, ventilation, and ICU admission with treatment.
Chow et al., 4/1/2021, retrospective, USA, North America, peer-reviewed, 38 authors.
risk of death, 47.0% lower, RR 0.53, p = 0.02, treatment 26 of 98 (26.5%), control 73 of 314 (23.2%), adjusted per study, Cox proportional hazards.
risk of mechanical ventilation, 44.0% lower, RR 0.56, p = 0.007, treatment 35 of 98 (35.7%), control 152 of 314 (48.4%), adjusted per study, Cox proportional hazards.
risk of ICU admission, 43.0% lower, RR 0.57, p = 0.007, treatment 38 of 98 (38.8%), control 160 of 314 (51.0%), adjusted per study, Cox proportional hazards.
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.
