hernias are more common in women vs men but they are still less frequent than
inguinal hernias in women.

such as appendicitis or cholecystitis.
G. Given the same underlying diagnosis for an acute abdominal disorder, the
elderly have about the same mortality rate as younger patients.
H. The elderly exhibit less pain and tenderness than younger patients, but
they are more likely to have fever and leukocytosis than are younger
patients.
I.
Diagnostic delays and pre-existing illnesses lead to a higher mortality in
elderly patients than in younger patients.
