SUPPLEMENTARY FIGURES
Supplementary Figure 1: All-Cause Mortality Meta-analysis Results for Studies Comparing
OMBP (With or Without Enema) Versus Enema or No preparation
CI = confidence interval; CrI = credibility interval; NA = not applicable; OMBP = oral mechanical bowel
preparation; OR = odds ratio.
The solid squares (and horizontal lines) indicate the point estimate of the OR (and the corresponding 95%
CI) for individual studies; the diamonds (and horizontal lines) indicate the summary estimate of the OR
(and corresponding 95% central CrI). The numbers of events and the sample size of each treatment group
are shown to the right of the plot. The dashed line indicates an OR of 1.
Supplementary Figure 2: Wound Infection Meta-analysis Results for Studies Comparing
OMBP (With or Without Enema) Versus Enema or No preparation
CI = confidence interval; CrI = credibility interval; NA = not available (could not be estimated); OMBP
= oral mechanical bowel preparation; OR = odds ratio.
The solid squares (and horizontal lines) indicate the point estimate of the OR (and the corresponding
95% CI) for individual studies; the diamonds (and horizontal lines) indicate the summary estimate of
the OR (and the corresponding 95% central CrI). The numbers of events and the sample size of each
treatment group are shown to the right of the plot. The dashed line indicates an OR of 1.
Supplementary Figure 3: Peritonitis/ Intra-Abdominal Abscess Meta-analysis Results for
Studies Comparing OMBP (With or Without Enema) Versus Enema or No preparation
CI = confidence interval; CrI = credibility interval; NA = not available (could not be estimated); OMBP =
oral mechanical bowel preparation; OR = odds ratio.
The solid squares (and horizontal lines) indicate the point estimate of the OR (and the corresponding 95%
CI) for individual studies; the diamonds (and horizontal lines) indicate the summary estimate of the OR
(and the corresponding 95% central CrI). The numbers of events and the sample size of each treatment
group are shown to the right of the plot. The dashed line indicates an OR of 1.
Supplementary Figure 4: Reoperation Meta-analysis Results for Studies Comparing OMBP
(With or Without Enema) Versus Enema or No preparation
CI = confidence interval; CrI = credibility interval; NA = not available (could not be estimated); OMBP =
oral mechanical bowel preparation; OR = odds ratio.
The solid squares (and horizontal lines) indicate the point estimate of the OR (and the corresponding 95%
CI) for individual studies; the diamonds (and horizontal lines) indicate the summary estimate of the OR
(and the corresponding 95% central CrI). The numbers of events and the sample size of each treatment
group are shown to the right of the plot. The dashed line indicates an OR of 1.
Supplementary Figure 5: Surgical Site Infection Meta-analysis Results for Studies
Comparing OMBP (With or Without Enema) Versus Enema or No preparation
CI = confidence interval; CrI = credibility interval; NA = not available (could not be estimated); OMBP =
oral mechanical bowel preparation; OR = odds ratio.
The solid squares (and horizontal lines) indicate the point estimate of the OR (and the corresponding 95%
CI) for individual studies; the diamonds (and horizontal lines) indicate the summary estimate of the OR
(and the corresponding 95% central CrI). The numbers of events and the sample size of each treatment
group are shown to the right of the plot. The dashed line indicates an OR of 1.
