  1. Subjects are assigned to journals and not specific papers. Note that in these models, a given URL could contribute to multiple subjects due to appearing in multiple journals which could also have multiple subject areas. Where possible, specific subjects were generalized (for example, "Computer Science, Interdisciplinary Applications" became "Computer Science"). Median survival estimated using R's survfit(). "NA" indicates that an upper 95% limit was unable to be computed.
