A: Ranking of the total number of scoliosis-related publications per country. Threshold of >100 published items. Study period from 1904 to 2007. 2B: Density-equalizing map illustrating the number of publications per country. The area of each country was scaled in proportion to its total number of scoliosis-related publications for period 1904 to 2007.
