Data Wranglingis a comprehensive process that involves transforming raw data into a format suitable for analysis. It encompasses several stages, including acquiring the data, structuring it, cleaning it, and validating it. The goal of data wrangling is to prepare data from diverse sources so it ca...

More specifically, the probability of disease introduction through different pathways is defined by (1) the probability of the infectious pathogen being present in the animal or biological vectors (e.g. mosquitoes, ticks, wildlife) or in/on mechanical vectors (e.g. air, food, equipment), (2)...
This was repeated separately for the low and high CIB groups. Bootstrapping with 2000 iterations was used for all causal mediation analyses. We performed all statistical analyses using R version 4.1.2 (R Core Team) and the dplyr and mediation packages....
