Sai et al[37]	2012	10	771	430 (55.8)	NR	14 (2.1)	Patients evaluated within 24 wk with surgery, colonoscopy, or barium enema
Sharma et al[38]	2014	11	3358	1970 (58.7)	220 (19.5)	22 (1.6)	Also examined uncomplicated vs complicated diverticulitis and found proportional estimate of risk of 0.7% and 10.8%, respectively
de Vries et al[39]	2014	9	2490	1468 (59)	278 (19.9)	17 (1.16)	Only examined patients presenting with uncomplicated diverticulitis
