Abstract

opplot generates a vertical bar chart to summarize a binary outcome in cluster survey data. The plot is known as an organ pipe plot. Each cluster is represented with a vertical bar. The shaded portion of the bar represents the proportion of respondents in that cluster whose value of yvar is 1. Clusters with the highest proportion of 1's (also known as coverage) are shown at the left side of the plot. Coverage decreases monotonically from left to right. Organ pipe plots were developed for the field of vaccination coverage surveys, but they can be helpful for any type of cluster survey with binary outcomes. The plots are useful for understanding the heterogeneity in cluster-level coverage, which is related to the intracluster correlation coefficient. The plots are also useful for identifying clusters with surprisingly low or surprisingly high coverage. The number of respondents per cluster is also displayed.
