Occult Hepatitis B Infection in Recent Immigrants to Italy: Occult B Infection in Immigrants.
Article in Journal of community health, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This study determined the prevalence and clinical features of occult hepatitis B infection (OBI) in a population of recent immigrants to Italy. Two hundred-five immigrants were tested for HBV-infection and were classified as seropositive-OBI or false-OBI. Biochemical/virological activities and imaging diagnostics were determined in anti-HBc-positive subjects. Among the tested subjects, 39.0% were anti-HBc-positive/HBsAg-negative; 11.2% had persistently normal ALT levels with mild detectable HBV-DNA, seropositive-OBI; 6.2% had slightly elevated ALT and positive serum HBV-DNA with a mean level of viral load: 3275 copies/mL-false-OBI. The total prevalence of OBI was 6.8%; 4.4% were seropositive-OBI and 2.4% were false-OBI. Diagnosis by echo-tomography was achieved in 35.7% OBI subjects with alterations of the hepatic echo-texture. We found a moderate prevalence of occult hepatitis B-infection in immigrants. Frequently, these subjects present false-OBI.
