Using augmented synthetic controls, we analyzed quarterly and semiannual rental listings and annual and semiannual sales within 300- and 500-m buffers around the OPCs.

We introduce a Bayesian bivariate spatial modeling framework for jointly analyzing early- and late-stage cancer incidence, allowing for both spatial correlation across areas and outcome correlation within areas to improve small-area estimation. Using population-based registry data aggregated at the small-area level, we estimate age-standardized incidence rates of early- and late-stage cancers across the study area and propose an inferential approach to identify priority sub-areas. We compare single-outcome and multivariate spatial formulations via Integrated Nested Laplace Approximation.

Recently, formal causal estimands designed to quantify vaccine waning have been proposed. These estimands can be bounded under weaker assumptions, but the bounds are often too wide to make claims about the presence of waning. We propose a different approach: a formal test to assess whether a treatment effect is constant over time at the individual level. This test provides a considerable power gain over existing approaches and is valid under interpretable assumptions in vaccine trials. We illustrate the increase in power through real and simulated examples, using 3 different approaches to compute the test statistics. Two of these approaches are based solely on summary data, accessible from existing clinical trials. Beyond our test, we also give new results that bound the waning effect.

Recent methods have been developed to mitigate measurement error bias in real-world endpoints; however, they rely on the existence of a validation sample, ie, data on a set of patients where both the \"true\" trial-like and \"mis-measured\" real-world measures are collected. We demonstrate how novel statistical methods can be leveraged as quantitative bias analyses (QBA) to contextualize real-world evidence findings when outcome measurement error is of concern, but validation samples are infeasible to collect. Quantitative bias analyses allow researchers to set plausible ranges for the amount of error when not directly measurable. We highlight how to conduct QBA with two recent methods, cumulative incidence curve correction and survival regression calibration, and illustrate how to generate plausible parameter values through simulation.
