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
Low positive predictive values of Neisseria gonorrhoeae nucleic acid amplification tests in low-prevalence populations are a major challenge for accurate diagnostics. It is therefore necessary to verify all positive N. gonorrhoeae results with a different assay and target gene, preferably using the same sample. The BD ProbeTec™ Q(x) Collection Kit for Endocervical or Lesion Specimens, which is recommended for BD Viper™ XTR, is incompatible with other commercial platforms. Therefore, a confirmatory PCR has not been available for samples received on this transport medium. To be able to verify results from these samples with another assay, our objective was to establish a procedure for using the DNA eluates from BD Viper™ XTR for further analysis. DNA eluates from BD Viper™ XTR were collected and analyzed in two in-house confirmatory real-time PCRs targeting the porA pseudogene and the opa multicopy gene. BD Viper™ XTR DNA eluates were analyzed directly and also after purification with the nucleic acid extraction system NucliSENS® easyMag®. Purification of BD Viper™ XTR DNA eluates with the nucleic acid extraction system NucliSENS® easyMag® provided a sensitivity of the in-house PCR comparable to BD Viper™. With the inclusion of two target genes in the confirmatory PCR, specific and reliable verification of results were obtained. This study presents a simple, inexpensive procedure which allows for rapid verification of gonorrhea from samples received on the BD ProbeTec™ Q(x) Collection Kit for Endocervical or Lesion Specimens.
