Importance

The Colonoscopy Versus Fecal Immunochemical Test in Reducing Mortality From Colorectal Cancer (CONFIRM) randomized clinical trial sought to recruit 50 000 adults into a study comparing colorectal cancer (CRC) mortality outcomes after randomization to either an annual fecal immunoc...

Background

Thrombosis and inflammation may contribute to morbidity and mortality among patients with coronavirus disease 2019 (Covid-19). We hypothesized that therapeutic-dose anticoagulation would improve outcomes in critically ill patients with Covid-19.

Methods

In an open-label, ad...

Importance

The efficacy of antiplatelet therapy in critically ill patients with COVID-19 is uncertain.

Objective

To determine whether antiplatelet therapy improves outcomes for critically ill adults with COVID-19.

Design, setting, and participants

In an ongoing adaptive platfor...

Importance

The evidence for benefit of convalescent plasma for critically ill patients with COVID-19 is inconclusive.

Objective

To determine whether convalescent plasma would improve outcomes for critically ill adults with COVID-19.

Design, setting, and participants

The ongoing...

Importance

Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19.

Objective

To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patien...

Background

The efficacy of interleukin-6 receptor antagonists in critically ill patients with coronavirus disease 2019 (Covid-19) is unclear.

Methods

We evaluated tocilizumab and sarilumab in an ongoing international, multifactorial, adaptive platform trial. Adult patients with Covid-...

Importance

The longer-term effects of therapies for the treatment of critically ill patients with COVID-19 are unknown.

Objective

To determine the effect of multiple interventions for critically ill adults with COVID-19 on longer-term outcomes.

Design, setting, and participants

Background

The efficacy of simvastatin in critically ill patients with coronavirus disease 2019 (Covid-19) is unclear.

Methods

In an ongoing international, multifactorial, adaptive platform, randomized, controlled trial, we evaluated simvastatin (80 mg daily) as compared with no stati...

Background

Thrombosis and inflammation may contribute to the risk of death and complications among patients with coronavirus disease 2019 (Covid-19). We hypothesized that therapeutic-dose anticoagulation may improve outcomes in noncritically ill patients who are hospitalized with Covid-19.

Importance

The efficacy of vitamin C for hospitalized patients with COVID-19 is uncertain.

Objective

To determine whether vitamin C improves outcomes for patients with COVID-19.

Design, setting, and participants

Two prospectively harmonized randomized clinical trials enrolled c...
