TL;DR: In this article, the authors developed a probabilistic model for settings where the test results are correlated, which they used to compute optimal pool sizes in the context of two-stage pool testing schemes.

TL;DR: Cumulative incidence-based definition of coverage yields a more accurate representation of the long-run treatment success and along with the World Health Organization and other definitions of coverage provides a better understanding of the HIV treatment progress.

TL;DR: Weintraub et al. as discussed by the authors developed innovative methodologies and tools that placed operations research and analytics at the forefront of the battle against the pandemic, including tools that provided data on the actual effects of lockdowns in different municipalities and over time; helped allocate limited intensive care unit (ICU) capacity; significantly increased the testing capacity and provided on-the-ground strategies for active screening of asymptomatic cases; and implemented a nationwide serology surveillance program that significantly influenced Chile's decisions regarding vaccine booster doses and also provided information of global relevance.
