  • Surgical Literature Analysis

Background:

  • Critical appraisal of scientific literature necessitates understanding statistical analysis principles.
  • A significant portion of published research may lack robust statistical methodology.

Purpose of the Study:

  • To review fundamental statistical concepts relevant to scientific literature appraisal.
  • To describe commonly used statistical tests in colon and rectal surgery research.

Main Methods:

  • Review of 190 articles relevant to colon and rectal surgery.
  • Analysis of the presence and type of statistical methods employed in the reviewed articles.
  • Description of basic statistical concepts and specific tests.

Main Results:

  • Only 29% of reviewed articles contained no statistical analysis.
  • Descriptive statistics were present in 24% of articles.
  • Formal statistical tests were utilized in 47% of the articles.

    • Conclusions:

    • A substantial number of articles in colon and rectal surgery literature lack formal statistical testing.
    • Familiarity with basic statistical concepts and tests like the t-test, chi-square, and nonparametric tests is essential for researchers and readers.
    • Improved statistical reporting and understanding can enhance the critical evaluation of surgical research.
