<p>Line graphs of the number of PubMed results for each HIT over time, (A) each year and (B) cumulatively. The number of publications on hospital information systems began to grow rapidly in the early part of the decade but has been variable. Overall, there are nearly twice as many HIS publications versus other HIT. (C, D) Corresponding graphs for programming languages. The number of publications using Perl grew rapidly in the early part of the decade and then stabilized, while the number of publications using Bioconductor and Python has grown more recently. Overall, Perl enjoys a nearly two-fold lead in total publications versus other languages.
