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
An indirect and a sandwich enzyme-linked immunosorbent assay (ELISA), employing long-chain lipopolysaccharides (LC-LPS) and crude boiled extract as antigens respectively, were evaluated for the detection of antibodies against Actinobacillus pleuropneumoniae serovars 1, 2, 5, 9 and 11 in pig sera. By testing sera from pigs experimentally infected with the 10 recognized serovars, both assays were proven to have comparable sensitivity and specificity. With sera from pigs immunized with vaccines containing antigens of A. pleuropneumoniae serovars 1, 2 and 5, the assays were found to have a good correlation. The high diagnostic sensitivity and specificity of the indirect ELISA, along with its efficiency and ease of standardization-especially when using well-characterized antigens such as LC-LPS-may make it a valuable tool for field diagnostics.
