The bibliometric measures included annual rates of authorships (), first\/last authorships (), monograph\u2010equivalents (), as well as the cumulative h\u2010index and contribution\u2010normalized ha\u2010index. Career age was defined by year of first publication. Productivity distributions were evaluated by career age using empirical cumulative distribution functions derived from 2016\u20132025 data. Era\u2010dependent fluctuations (1990\u20132025) were examined using age\u2010normalized metrics and trends in authorship team size. Tabulated bibliometrics as a function of career age are provided for evaluation of individual performance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Productivity increased substantially with career age, peaking in late career. Senior faculty produced approximately two\u2010fold higher annual output than early\u2010career peers. At career ages of 1, 10, 20, 30, and 40 years, the median bibliometric rates were\u00a0\u00a0=\u00a0(1.2, 1.6, 2.5, 2.5,1.8) year\n                      <jats:sup>\u22121<\/jats:sup>\n                      ,\u00a0\u00a0=\u00a0(0.4, 0.4, 0.5, 0.5,0.2) year\n                      <jats:sup>\u22121<\/jats:sup>\n                      ,\u00a0\u00a0=\u00a0(0.2, 0.2, 0.3, 0.3,0.3) year\n                      <jats:sup>\u22121<\/jats:sup>\n                      , h\u2010index\u00a0=\u00a0(0, 7, 15, 23,43), and ha\u2010index\u00a0=\u00a0(0, 3.3, 6.0, 9.4,15.0).\u00a0Era\u2010based effects were substantial.

Career\u2010age\u2010based percentile benchmarks provide a more balanced framework for evaluating academic performance than unadjusted bibliometric comparisons, especially for early\u2010career investigators. Due to changes in authorship norms over time, first\/last authorships, monograph equivalents, and ha\u2010index may provide more accurate and equitable assessments of research performance than authorships or h\u2010index.<\/jats:p>\n
