TL;DR: Among patients with severe or life-threatening COVID-19, convalescent plasma therapy added to standard treatment, compared with standard treatment alone, did not result in a statistically significant improvement in time to clinical improvement within 28 days.

TL;DR: Wu et al. as mentioned in this paper used a multistage, population-stratified, cluster random sampling method to determine the seroprevalence and kinetics of anti-SARS-CoV-2 antibodies at population level in Wuhan to inform the development of vaccination strategies.

TL;DR: Wang et al. as mentioned in this paper used a bilinear interpolation approach to estimate each participant's daily ambient particulate matter pollution and meteorological variables exposure based on their geocoded residential address and a 10 km × 10 km grid from China High Air Pollutants and the fifth generation of European ReAnalysis-Land reanalysis data set.

TL;DR: Wang et al. as mentioned in this paper used a multivariable competing risk survival analysis to identify several important predictors of progression to severe COVID-19-rather than to recovery-among patients in community isolation.

TL;DR: Age, an elevated neutrophil-to-lymphocyte ratio and high sensitivity cardiac troponin I can help clinicians identify patients with severe COVID-19 at an early stage.
