Mortality -32% Improvement Relative Risk Aspirin for COVID-19  Miele et al.  Prophylaxis Is prophylaxis with aspirin beneficial for COVID-19?

Retrospective 485,779 osteoarthritis patients in the US showing lower mortality with non-aspirin NSAIDs and celecoxib, and higher mortality with aspirin. Aspirin was associated with higher hospitalization in COVID-positive and COVID-negative patients. Comparison of the COVID-positive and COVID-negative results suggests significant residual confounding.
Standard of Care (SOC): SOC for COVID-19 in the study country, the USA, is very poor with very low average efficacy for approved treatments1. Only expensive, high-profit treatments were approved. Low-cost treatments were excluded, reducing the probability of treatment—especially early—due to access and cost barriers, and eliminating complementary and synergistic benefits seen with many low-cost treatments.
This study is excluded in the after exclusion results of meta analysis: substantial unadjusted confounding by indication possible.
Study covers aspirin, ibuprofen, and indomethacin.

Effect of background therapy with Non-steroidal anti-inflammatory drugs (NSAIDs) and other anti-inflammatory agents on COVID-19 outcomes

Background: Inflammation plays a complex, incompletely understood role in the pathogenesis of acute COVID-19 and Post-Acute Sequelae of SARS-CoV-2 infection (PASC or "Long COVID"). Systemic acute inflammation resulting in cytokine storm, hypercoagulability and endothelial damage is thought to be a central mechanism for severe morbidity and mortality in acute COVID-19. Anti-inflammatory medications taken routinely for chronic conditions prior to contracting COVID-19 ("background medications") may modulate acute COVID-19 outcomes. Methods: Using data from the National COVID Cohort Collaborative (N3C) enclave, we estimated effects of six classes of background medications on acute COVID outcomes. Medication classes included aspirin, celecoxib, other NSAIDS, steroids, immune suppressants, and antidepressants. Acute COVID outcomes included probability of hospital admission, inpatient mortality, and mortality among diagnosed COVID patients. Each medication class was compared to benzodiazepines (excluding midazolam) which served as a comparator/control. Only adult COVID patients with pre-existing osteoarthritis and without any diagnosed autoimmune disease were included in the analyses. Random effects logistic regression models were used to adjust for covariates and data contributing organization. Medication effects also were estimated for COVID-negative cases. Results: Non-aspirin NSAIDS were associated with lower mortality among diagnosed COVID-19 patients: adjusted Odds Ratio (aOR)=0.32 (p=.032) for celecoxib; aOR=0.51 (p<.001) for NSAIDS other than aspirin and celecoxib. For inpatient mortality: aOR=0.34 (p=.060) for celecoxib and aOR=0.74 (p=.200) for other non-aspirin NSAIDS. Similar effects were observed for COVID-negative cases, including for inpatient mortality: aOR=0.21 (p<.001) for celecoxib and .
