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
introductionThis study aims to determine the rate of anti-hepatitis B virus coverage (anti-HBV) and the prevalence of Ag HBs among Beninese soldiers participating in military missions in Ivory Coast.
methodsWe conducted a cross-sectional study within the Beninese battalion based in Anankouakouté in the Ivory Coast. The company's soldiers were administered interview-based questionnaire during a health education session. It focused on socio-demographic data, risk factors for infection and a history of vaccination against hepatitis B. Samples were analyzed for Ag HBs and HBS antibodies. Sodiers positive for AgHBs underwent complementary tests (ALT, HBeAg, anti-HBe antibody, IgM anti-HBc antibody and HBV DNA using PCR).
resultsOne hundred seventy-five soldiers were enrolled in this study (with an average age of 31 years, ranging between 23 and 52 years; sex-ratio 5.73). Protective anti-HB antibody levels were found in 41 soldiers (23.4%). Some soldiers had had B hepatitis and had developed immunity to the virus (25 cases/41) while others had developed immunity after vaccination (16 cases/41). Eighteen soldiers (10.3%) had HBV (HBsAg+) infection. This infection was chronic (IgM anti-HBc - and anti-HBc antibody total + in 18 cases/18). Among the infected soldiers, 4 had elevated aminotransferase levels, 4 were found HBeAg-positive and 4 had elevated viremia levels (HBV DNA >2000IU/ml).
conclusionThe prevalence of Ag HBs among Beninese soldiers participating in military missions is high. However, immunization coverage is low. Intervention strategies should be implemented in order to treat subjects who meet the criteria and to vaccinate the unimmunized patients.
