Study Title and Description
Conservative Treatment in Diverticulitis Patients with Pericolic Extraluminal Air and the Role of Antibiotic Treatment.
Key Questions Addressed
2 | KEY QUESTION 2 KQ 2: What are the benefits and harms of various treatment options for the treatment of acute diverticulitis? KQ 2a. For patients with acute uncomplicated diverticulitis, what are the effectiveness and harms of hospitalization versus outpatient management of the acute episode? • Do the effects and harms vary by patient characteristics, presentation or course of illness, or other factors? KQ 2b. For patients with acute uncomplicated or complicated diverticulitis, what are the effects, comparative effects, and harms of antibiotics? • Do the effects and harms vary between patients with complicated or uncomplicated diverticulitis? • Do the (comparative) effects and harms vary by route of administration of antibiotics, type of antibiotic, and duration of course of antibiotics? • Do the (comparative) effects and harms vary by patient characteristics, presentation or course of illness, or other factors? KQ 2c. For patients with acute complicated diverticulitis, what are the effects and harms of interventional radiology procedures compared with conservative management? • Do the effects and harms vary by patient characteristics, presentation or course of illness, or other factors? |

Arms
Number | Title | Description | Comments |
---|---|---|---|
1 | Antibiotics: Multiple (discretionary or undefined) | For the patients from the retrospective cohort, they were assigned to antibiotic treatment group if antibiotic treatment had been started within 24 h after presentation. For DIABOLO study, IV amoxicillin–clavulanic acid was chosen as broad-spectrum antibiotic treatment of choice. | |
2 | No intervention (non-placebo) | Observational treatment |

Quality Dimensions
Dimension | Value | Notes | Comments |
---|---|---|---|
Q14: Cochrane - Random sequence generation (selection bias): Selection bias (biased allocation to interventions) due to inadequate generation of a randomized sequence | |||
Q15: Cochrane - Allocation concealment (selection bias): Selection bias (biased allocation to interventions) due to inadequate concealment of allocations prior to assignment | |||
Q16: Cochrane - Blinding of participants (performance bias): Performance bias due to knowledge of the allocated interventions by participants during the study | |||
Q17: Cochrane - Blinding of personnel/ care providers (performance bias): Performance bias due to knowledge of the allocated interventions by personnel/care providers during the study. | |||
Q18: Cochrane - FOR OBJECTIVE OUTCOMES - Blinding of outcome assessor (detection bias): Detection bias due to knowledge of the allocated interventions by outcome assessors. | |||
Q20: Cochrane - Incomplete outcome data (attrition bias): Attrition bias due to amount, nature or handling of incomplete outcome data | |||
Q21: Cochrane - Selective Reporting (reporting bias): Reporting bias due to selective outcome reporting | |||
Q22: Cochrane - Other Bias: Bias due to problems not covered elsewhere in the table. If yes, describe them in the Notes. | |||
Q1: ROBINS-I 1.1 Is there potential for confounding of the effect of intervention in this study? | |||
Q3: ROBINS-I 1.4. Did the authors use an appropriate analysis method that controlled for all the important confounding domains? | |||
Q4: ROBINS-I 1.5. If Y/PY to 1.4: Were confounding domains that were controlled for measured validly and reliably by the variables available in this study? | |||
Q5: ROBINS-I 1.6. Did the authors control for any post-intervention variables that could have been affected by the intervention? | |||
Q6: ROBINS-I - Risk of bias judgement for BIAS DUE TO CONFOUNDING | |||
Q7: ROBINS-I 2.1. Was selection of participants into the study (or into the analysis) based on participant characteristics observed after the start of intervention? | |||
Q8: ROBINS-I 2.2. If Y/PY to 2.1: Were the post-intervention variables that influenced selection likely to be associated with intervention? | |||
Q9: ROBINS-I 2.3 If Y/PY to 2.2: Were the post-intervention variables that influenced selection likely to be influenced by the outcome or a cause of the outcome? | |||
Q10: ROBINS-I 2.4. Do start of follow-up and start of intervention coincide for most participants? | |||
Q12: ROBINS-I 2.5. If Y/PY to 2.2 and 2.3, or N/PN to 2.4: Were adjustment techniques used that are likely to correct for the presence of selection biases? | |||
