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

We report the results of an evaluation of the LIAISON Treponema pallidum-specific assay, a one-step sandwich chemiluminescence immunoassay (CLIA), as a screening test and as a confirmatory test for the diagnosis of syphilis. The assay was compared with the CAPTIA Syphilis-G enzyme immunoassay (EIA) and with a testing algorithm that also included the rapid plasma reagin (RPR) and T. pallidum particle agglutination (PA) assays. As a screening test, the CLIA showed levels of agreement with the EIA and with the algorithm, respectively, of 94.1 and 100% for 51 samples from patients with primary or secondary syphilis, 93.2 and 98.7% for 999 samples sent to the laboratory for routine syphilis testing, 84.5 and 94.0% for 200 samples from human immunodeficiency virus-positive patients, 98.0 and 100% for 200 samples from pregnant patients, and 94.3 and 98.3% for 992 samples from apparently healthy adults. As a confirmatory test, the CLIA showed 99% agreement with the EIA for 204 RPR-positive samples. After resolution with further T. pallidum PA testing and the discarding of one sample of insufficient quantity, there was 100% agreement for the remaining 203 samples. For the total group of 2,645 samples, the overall relative sensitivity was 95.8% and the relative specificity was 99.1%. We conclude that the LIAISON CLIA demonstrated excellent sensitivity and specificity when evaluated as a confirmatory test and as a screening test for syphilis among various patient populations, including specific populations with reportedly increased rates of false-positive nontreponemal test results.
