Distribution of GHAs by year of publication of documents. This figure shows the distribution of GHAs by year of publication of documents in which they state that they are in favor of free care at the point of delivery or in favor of abolition of user fees. The size of each year block is proportional to the number of documents published that year. When the number of documents published by a GHA is more than one, the total number is indicated in brackets. The name of the GHA is highlighted when it is the first time it takes a positive stance from 2005.
