Authorship to Acknowledge our Biostatistics Work


Any biostatistician conducting analysis, or otherwise making a significant contribution will:

  • Be a co-author on the publication to acknowledge their intellectual contribution, using their primary appointment affiliation
  • Analyze data collected for publication and abstracts only after study completion, to maintain study and statistical integrity
  • Collaborate with you in structuring the presentation of results and write the statistical methods section of your paper
  • Review your publication and any revisions prior to submission
  • Assist with revisions, keeping in mind your revision deadlines

The CBC abides by the International Committee of Medical Journal Editors (ICMJE) guidelines concerning authorship.

Guidelines for order of listed authors

The order in which our biostatistician is listed as author depends on extent of contribution:

  • First author: Biostatistician plays major role in project development or hypothesis generation, (when existing data) substantially changes direction of hypothesis and corresponding analysis, provides a unique contribution, conducts analysis, and writes large portion of your paper.
  • Second author: Biostatistician plays major role in project development, offers statistical expertise needed for your research, or conducts substantial and/or complex analysis of data. Typical position for biostatistician involved in life cycle of project or who has unique analytic expertise (e.g., mediation analysis, microbiome, genomics).
  • Middle-listed author: Biostatistician does not necessarily collaborate in design of study, but conducts data analysis, writes statistical methods section, and assists in interpreting results for conclusion.
  • Senior author: Biostatistician provides significant mentoring to first author, offering guidance for first author to conduct analysis, or plays major role in helping first author design the study. Generally has been substantial one-on-one meeting time as well as additional analysis and paper writing support beyond typical collaborative role.
  • Junior or student biostatisticians: Biostatistician mentored by senior statistician, senior statistician immediately follows junior statistician within authorship line (e.g., if junior statistician is second author, mentoring statistician would generally be listed as third author).
