Molecular characterization of duck hepatitis B virus isolates from South African ducks.
Article in Virus genes, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
The objective of the study was to characterize the genome of duck hepatitis B virus (DHBV) isolates from South African Pekin ducks. Duck serum and liver samples were collected from two commercial duck farms from geographically distinct regions of South Africa. In total, 498 duck serum samples were tested for the presence of DHBV DNA using either sub-genomic or full-length polymerase chain reaction (PCR) assays. The overall prevalence of DHBV infection in South African ducks was 47%. In addition, 30% of 59 liver tissues tested were DHBV DNA-positive. Six randomly selected serum or liver samples were used to clone and sequence the genomes of the South African DHBV strains. All six isolates had DHBV genomes of 3,021 nucleotides with three characteristic overlapping reading frames encoding the polymerase, surface and core gene products. No X-like gene with a traditional start codon was found. Following phylogenetic analysis, the South African DHBV isolates clustered with DHBV isolates from other "Western" countries, including United States of America, Canada, Germany and India. On translation of the open reading frames, the South African isolates were found to share signature amino acids in the polymerase and surface genes with the "Western" country isolates as opposed to those of Chinese DHBV isolates.
