Medvane

 The present state and historical trends of biomedical research in the Harvard community.

Subjects

The chart below shows the 10 most frequently published subjects of a given time period. The time periods — All Time, Last Year, Last 5 years, or Last 10 years — are accessible using the tabs above. The chart shows the trend for those 12 subjects over time. The x axis is year, and the y axis is an arbitrary unit of topic frequency normalized by the total number of articles in PubMed/MEDLINE.
subject flow

The word cloud below comprises the top 20 subjects in which Harvard community researchers have been published most often.

Word clouds are alphabetical lists that represent relative frequency of each term through larger (more frequent) and smaller (less frequent) text sizes.

Rising or Falling Subjects

Below are the 55 subjects on which the number of articles has significantly changed compared to other time periods as indicated by the column heads. The arrows represent the percent increase (red) or decrease (blue) in the number of articles on that subject. For example, the first row for 'Genetic Predisposition to Disease' indicates a 1% increase last year compared to the last 5 years.
