Missing data pattern for variables included in the analysis.
The bar chart on the left depicts the proportion of data missing for each variable. The graph on the right displays the different data patterns, with missing data in white and available data in blue. The histogram shows the frequency of the individual data patterns, with complete cases accounting for 28.0% of the total sample.
