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

objectiveCirculating tumor human papillomavirus (HPV) DNA (ctHPV DNA) has shown clinical utility in advanced cervical cancer; however, its role in surgically resected disease remains unclear. We evaluated the detectability and clinicopathological associations of ctHPV DNA in preoperative plasma from patients with surgically resected cervical cancer using digital polymerase chain reaction (dPCR).

methodsWe analyzed 49 surgically resected cervical cancer patients. HPV genotyping of formalin-fixed paraffin-embedded tumor tissues was performed using both PGMY09/11 consensus PCR and novel genotype-specific dPCR assays targeting 6 high-risk HPV types (16, 18, 31, 39, 45, and 52). Plasma cell-free DNA was analyzed using dPCR for HPV genotypes. Associations between ctHPV DNA copy number and clinicopathological features were evaluated.

resultsHPV genotypes were identified in 42 of 49 tumor tissues (85.7%), with dPCR showing superior sensitivity (95.8%) compared to the PGMY method (77.6%). ctHPV DNA was detected in 12 of 42 evaluable plasma samples (28.6%), and plasma genotypes were concordant with those of the corresponding tumor tissues. ctHPV DNA copy numbers were significantly higher in cases with lymphovascular invasion (p=0.034) and lymph node metastasis (p=0.010), but were not correlated with tumor size, stage, or histologic type. ctHPV DNA was more consistently detectable than

conclusionThis study highlights ctHPV DNA as a promising noninvasive biomarker in surgically resected cervical cancer. Its association with lymphovascular invasion and lymph node metastasis supports its potential role in preoperative risk stratification and personalized surgical planning.
