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
Dengue is a viral disease with a broad spectrum of clinical manifestations. Its severity is associated with risk factors such as periods of endemicity, although the extent of this contribution is unclear. In the present study, the characteristics of the clinical course and differences in the occurrence of severe and lethal outcomes were assessed by the degree of endemicity in patients with dengue treated in health institutions in Cali, Colombia, between 2019 and 2022. A longitudinal, observational-historical, single-cohort study was conducted. Analysis involved evaluating clinical complications during epidemic and endemic periods. Mortality, cumulative incidence of hospital or intensive care unit (ICU) admission, and survival time were estimated using the competing risks method. A total of 1,038 dengue cases were included. Patients with severe dengue and those with warning signs (WS) were consulted up to 6 or 5 days after symptom onset, respectively. A hospital stay of 2.0 days (Quartile [Q]1-Q3: 2-4 days) and an ICU stay of 4.5 days (SD ± 3.9 days) were estimated. A mortality rate of 5.5% was obtained for severe dengue, and a mortality rate of 0.4% was identified for patients with WS. In 2020 and 2021, the probability of hospitalization was 20% from initial contact. The likelihood of dying within 10 days after initial contact was 0% in 2019 and 11.2% (95% CI: 4.0-22.5%) in 2020. The incidence of hospitalization, number of hospital days, and ICU stays due to dengue varied by epidemiological year in a high-endemicity area. The probability of severe and lethal clinical outcomes was higher during 2020 and 2021.
