Caterpillar plot and map characterising departmental variations in data completeness. a The grey markers are the observed departmental proportions of missing baseline DAS28 data. The blue markers are the predicted departmental proportions after adjustment for case mix and applying a shrinkage to account for the small overall sample size, with 95% confidence intervals in red. The black horizontal line represents the overall sample mean. The further to the right along the x-axis indicates worse performance by a department, i.e. a greater proportion of missing DAS28 data. b Locations of outlier departments mapped across England and Wales. Red markers represent departments with high outlier levels of missing baseline DAS-28. Green markers represent low outliers
