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
backgroundThe methylation of paired boxed gene 1 (PAX1) and zinc finger protein 582 (ZNF582) has been proved to have good diagnostic efficacy to detect cervical precancerous lesions in Asian populations, but their performance in Dutch populations is still unclear. We assessed PAX1 and ZNF582 methylation in both Dutch and Chinese cohorts.
methodsCervical scrapings were evaluated from 2 independent groups. The Dutch cohort (population-based screening) provided 190 abnormal cytology scrapings, and 138 cases tested positive for high-risk human papillomavirus (hrHPV). The hospital-based Chinese cohort included 246 specimens (205 abnormal cytology and 227 hrHPV+). Quantitative methylation-specific PCR was employed to analyze methylation.
resultsPAX1 and ZNF582 methylation showed high specificity of 91% to 97% with moderate sensitivity of 43% to 61% for cervical intraepithelial neoplasia (CIN) 2 or worse (CIN2+) in abnormal cytology and hrHPV+ samples in both cohorts. Sensitivity for CIN3+ increased to 55% to 86% but with lower specificity (85%-93%). For detecting CIN2+, PAX1/ZNF582 methylation performed similarly in Dutch and Chinese cohorts. However, for CIN3+, the Chinese cohort showed significantly higher sensitivity, with comparable specificity. We also evaluated combining these genes with our established markers (C13ORF18, JAM3, and ZSCAN1). The best diagnostic performance was achieved by combining PAX1 or ZNF582 with JAM3 in the Dutch cohort.
conclusionsIn conclusion, regardless of race or geography, methylation of PAX1 or ZNF582 is highly specific for detecting CIN2+/CIN3+ lesions in hrHPV+ or cytologically abnormal scrapings. Triage testing using these markers might significantly reduce immediate colposcopies. IMPACT: PAX1/ZNF582 methylation triage for cytology+/hrHPV+ scrapings may reduce immediate colposcopies.
