Thank you Dr. Davidson and co authors for allowing us to learn from your studies. Among participants in the antibiotic group, 41% of those who required appendectomy had appendicolith and 25 % within the same group did not have appendicolith and still underwent appendectomy following antibiotic treatment. What other factors/common variable could have contributed to a higher risk of future surgery in participants without appendicolith.
