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

backgroundThis study aimed to determine the prevalence of Hepatitis B Virus (HBV) infection among municipal waste collectors (MWCs) and to identify associated risk factors in Aden, Yemen.

methodsAn analytical cross-sectional study was conducted among 100 MWCs. Blood samples were collected and tested for HBsAg using the Cobas technique.

resultsThe overall prevalence of HBV infection was 5.0%, with a higher clustering of 40% observed in the Khormaksar district. A significant association was found between HBV infection and biomedical waste exposure (OR: 20.44, 95% CI: 2.44-171.5; p = 0.019). MWCs in the age group 25-35 years had three times or more risk of HBV infection (OR: 3.8, 95% CI: 0.598-23.88; p = 0.158). Significant risk was also noted among those whose duration of work was >20 years and 10-20 years (OR: 2.09 and 2.3, 95% CI: 0.328-13.27 and 0.359-14.106; p = 0.367 and 0.332), respectively. Exposure to catheterization and needle-stick injuries was significantly associated with HBV positivity (OR: 15.2 and 91; 95% CI: 20.195-117.85 and UD; p = 0.02 and 0.0001), respectively. Clinically, HBV infection was also significantly associated with fever (p = 0.0001), vomiting (p = 0.0001), nausea (p = 0.001), loss of appetite (p = 0.0001), abdominal pain (p = 0.001), and jaundice (p = 0.005).

conclusionThe prevalence of HBV infection in this study was relatively lower than most global findings. MWCs exposed to biomedical waste had the highest HBV positivity rates. Needle-stick injuries and catheterization may significantly increase the risk of infection. Mandatory screening and vaccination for HBV should be implemented for all municipal waste collectors to reduce the risk of infection.
