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
Introduction: Leptospirosis is a globally distributed zoonosis, particularly prevalent in tropical and subtropical regions, with epidemic potential during the rainy season. It is caused by pathogenic Leptospira species and produces a wide clinical spectrum, ranging from mild febrile illness to severe, life-threatening disease. Objective: To describe the clinical and epidemiological characteristics of hospitalized patients with serologically supported leptospirosis in Durán, Guayas province, Ecuador. Methods: A descriptive, cross-sectional study was conducted at the Hospital General Dr. Enrique Ortega Moreira between January and June 2023. Patients aged 15 years or older with fever and positive IgM serology for leptospirosis were included. Data were obtained from anonymized medical records. Categorical variables were summarized as frequencies and percentages, and continuous variables as medians with interquartile ranges (IQR). Group comparisons used the Pearson chi-square or Fisher exact test for categorical variables and the Mann-Whitney U test for continuous variables. Results: Forty-eight patients met the inclusion criteria. Most were male (58.3%) and aged 15-39 years (85.5%). The most frequent symptoms were fever (93.8%) and diarrhea (83.3%). The median duration of fever was 17 days (IQR 8-21), reaching up to 60 days. Concurrent dengue IgM positivity was identified in 22.9% of patients and was associated with a longer median fever duration (19 vs 16 days; p=0.036). Frequent laboratory abnormalities included hypoalbuminemia (86.4%), hyponatremia (82.9%), hypokalemia (55.3%), thrombocytopenia (54.2%), and anemia (54.2%). The median hospital stay was 7 days (IQR 5-8). Conclusions: Hospitalized leptospirosis cases in Durán during the 2023 rainy season showed frequent gastrointestinal manifestations, laboratory abnormalities, prolonged fever, and substantial dengue IgM positivity. These findings highlight diagnostic challenges in endemic coastal settings and support the need for strengthened surveillance, systematic evaluation of co-circulating infections, and national clinical practice guidelines for leptospirosis.
