Content of biased words in fundamental versus clinical research journals. The data are normalized by dividing the total word score obtained for an article by the total number of words contained in that same article. The median, 25th, 75th, percentiles are shown. The data show that there was a significant increase in the use of biased words over the past 20 years in the fundamental science journals but not in clinical science journals Statistical significance was assessed by Student T-test and corrected for multiple comparisons.
