Incidence of acute pancreatitis among hospitalized patients with dengue: A systematic review and meta-analysis.
Synthesis in PLoS neglected tropical diseases, 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
backgroundAcute pancreatitis (AP) is an under-recognized but clinically relevant complication of dengue fever (DF), associated with rapid clinical deterioration and increased risk of mortality. However, the true incidence of this condition remains uncertain.
methodsFollowing PRISMA 2020 guidelines, we systematically searched PubMed, Web of Science, Embase and China National Knowledge Infrastructure (CNKI) up to May 2025 for observational studies reporting AP among DF hospitalized patients. Eligible studies were identified according to predefined inclusion and exclusion criteria based on the Population, Intervention, Comparison, Outcome, and Study design (PICOS) framework. Two reviewers independently screened the literature and assessed study quality using the Newcastle-Ottawa Scale (NOS). Pooled incidence rates were estimated using random or common effect models depending on heterogeneity.
resultsEight observational studies from five countries, comprising 1,078 hospitalized patients with DF, were included. Among them, 135 were diagnosed with AP. The pooled incidence of AP complicating DF was 12.4% (95% CI: 10.5-14.4%). Subgroup analysis suggested a higher incidence in studies with ≥100 participants compared to smaller cohorts (13.5% vs. 8.3%, P = 0.03). No evidence of significant publication bias was detected.
conclusionDF-associated AP represents a clinically important complication, given the global burden of dengue and the potential severity of AP. Our findings underscore the importance of considering pancreatic enzyme testing, supplemented by imaging when clinically warranted, in dengue patients with persistent or severe abdominal symptoms and/or features of severe dengue. Large-scale, multicenter prospective studies are warranted to establish the true incidence and case-fatality risk, thereby informing evidence-based prevention and management strategies.
