The attributable fraction among the exposed (\textbf{AF}), also known as the attributable risk or excess fraction among the exposed, is the proportion of disease cases among th…
Estimating Causal Effects of HIV Prevention Interventions with Interference in Network-based Studies among People Who Inject Drugs
TingFang Lee, Ashley L. Buchanan, Natallia V. Katenka +4
Evaluating causal effects in the presence of interference is challenging in network-based studies of hard-to-reach populations. Like many such populations, people who inject drugs…
Estimands and Inference in Cluster-Randomized Vaccine Trials
Kayla W. Kilpatrick, Michael G. Hudgens, M. Elizabeth Halloran
Cluster-randomized trials are often conducted to assess vaccine effects. Defining estimands of interest before conducting a trial is integral to the alignment between a study's obj…
Comparing Biomarkers as Trial Level General Surrogates
Erin E. Gabriel, Michael J. Daniels, M. Elizabeth Halloran
An intermediate response measure that accurately predicts efficacy in a new setting can reduce trial cost and time to product licensure. In this paper, we define a trial level gene…
Estimating within-school contact networks to understand influenza transmission
Gail E. Potter, Mark S. Handcock, Ira M. Longini +1
Many epidemic models approximate social contact behavior by assuming random mixing within mixing groups (e.g., homes, schools and workplaces). The effect of more realistic social n…
