Human leptospirosis in the central division of Fiji: a retrospective epidemiological study.

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
backgroundLeptospirosis is a major cause of human disease in Fiji. However, the epidemiology is poorly defined. This study was conducted to determine the epidemiology of human leptospirosis in the Central Division and to characterize the largest urban outbreak in Fiji.
methodsA retrospective study was conducted using routine leptospirosis surveillance data collected from 1 January 2012 through 30 June 2020. Descriptive analysis was performed to evaluate changes in demographic characteristics and incidence over time.
resultsA total of 2248 cases were reported over the 8.5-y study period. Average annual incidence was 73.9 cases per 100 000 population, with the annual incidence ranging from 45.6 cases per 100 000 population in 2012 to 177.2 cases per 100 000 population in 2019. Overall, most cases were indigenous Fijians (82.6%) and males (53.3%). The proportion of females increased steadily from 37.8% in 2012 to 50.3% in 2020. On 28 January 2019, an outbreak of leptospirosis was declared in the Central Division. During this outbreak, the proportion of female cases (50.5%) was higher and cases among Fijians of Indian descent also increased (18.3%).
conclusionsStudy findings demonstrate changes in the epidemiology of leptospirosis in the Central Division. Increasing incidence in urban settings and among population groups previously considered low risk (female and Fijians of Indian descent) indicates shifts in risk factors and transmission patterns that warrant review of existing measures and strategies for nationwide disease control.
