Predictive factors for conservative treatment failure of acute complicated diverticulitis: a single-center retrospective analysis.
Article in Updates in surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
According to WSES guidelines conservative/non-operative treatment is the first-line therapy for acute complicated diverticulitis (ACD) but failure may represent a challenge in terms of hospitalization, medical costs, morbidities, and mortality. This study aimed to evaluate failure rates following non-operative management of acute complicated diverticulitis and to examine possible predictive factors for failure. We retrospectively analyzed all patients with a diagnosis of diverticulitis consecutively admitted to our Institution from 1 January 2017 to 31 December 2021. Patient demographics, blood inflammatory markers, radiological findings, management, and outcomes were evaluated.A total of 164 patients were included, 34 had uncomplicated diverticulitis and 130 had ACD. Among those with ACD, 18 patients underwent urgent surgery and 112 (WSES 1a n = 54, 1b n = 19, 2a n = 31, 2b n = 8) underwent conservative/nonoperative treatment, consisted of intravenous antibiotics with or without percutaneous drainage. Twenty-three patients (20.5%) failed conservative treatment. Univariate analysis revealed that male sex, obesity (BMI>30), low performance status (ASA > 2), and intra-abdominal abscess greater than 4 cm on CT scan, were significantly associated with conservative treatment failure. Multivariate analysis proved that obesity[OR 2.92; 95%CI 1.104-7.702; p-value 0.046] and intra-abdominal abscess > 4 cm [OR 3.66; 95%CI 1.386-9.672; p-value 0.014], were possible predictive factors of conservative treatment failure.Conservative/non-operative treatment of acute complicated.
