MEDICAL CARE
Figure 2 plots the annual numbers of
articles in medical and nonmedical journals.
The purpose is to examine the proportion
of the literature which has been intended
primarily for a physician audience
anid how this propoirtion has changed over
time. While the time paths follow each
other *losely, the graph shows a shift from a
rough parity prior to 1973 to a clear majority
of medical journal articles after 1973. In
other words, the rate of growth of the iedical
literature 1 -s exceeded that of tite
nonmedical journal literature. particularly
in receait years. This shift is statistically
significant (p = 0.05). (See Table 1.)
In c-ategorizing references by publication
vehicle, we kept track of a subset of
medical articles, nantely those published
in the New Eingla.id Journwl of .Medicirie.
