1 · What the graph read from it

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.

2 · The registry

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

backgroundLassa fever (LF), is a viral hemorrhagic illness endemic to West Africa and poses significant public health challenges. This study explores and identifies socioeconomic, and environmental markers contributing to transmission of LF in Lower Bambara Chiefdom, Kenema District, Eastern Sierra Leone.

methodsA descriptive cross-sectional quantitative survey was used, and through stratified sampling and a systematic data collection approach, we selected 26 enumeration areas (EAs) generating 2,167 households. A structured questionnaire was administered to capture respondents' demographics, community characteristics, and LF-related risk factors. Statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS). These included descriptive statistics to summarize the data, Chi-square tests to assess associations between categorical variables, and bivariate analyses specifically cross-tabulations and Chi-square tests to identify potential risk factors and correlations between sociodemographic/environmental variables and LF transmission.

resultsLess-bushy surroundings (53.9% to 73.5%); common mixed farming practice (61.5%); standpipes water source (40.5%) and waste burning practice (77.3%) are the most dominant environmental markers. Socioeconomic markers: farming (53.9%); construction materials included mud walls (72.0%) and zinc roofing (90.0%). Logging activities (36.9%) were conducted close to residential areas, with an average distance of just 14.7 m. Demographic variables sex, age, education, occupation, and relationship to the household head were statistically significant to LF transmission (p < 0.05). Environmental and socioeconomic markers such as farming practices, construction materials, palm-fruit storage, slashing and burning activities were significant (p < 0.05) LF transmission markers.

conclusionIn conclusion, demographic factors and poor environmental and socioeconomic practices like inadequate waste disposal, close proximity to logging sites and unsafe farming practices were significantly associated with LF transmission. These findings highlight areas that community education and environmental sanitation should be prioritised by public health policymakers and community-based prevention programs.
