Genotype-Specific HPV E6/E7 mRNA Triage Improves Risk Stratification and Reduces Referrals in DNA-Positive ASC-US/LSIL: A Real-World Cohort from Nordland, Norway.
Article in Pathogens (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
HPV DNA-positive women with ASC-US/LSIL cytology represent a heterogeneous risk group in cervical screening and require efficient triage. We evaluated a genotype-specific 7-type HPV E6/E7 mRNA assay (PreTect HPV-Proofer 7; types 16/18/31/33/45/52/58) in a real-world quality-assurance cohort at Nordland Hospital (Bodø, Norway). Among HPV-positive women with ASC-US/LSIL reflex cytology, 225 had sufficient residual liquid-based cytology material and a valid mRNA result; 175 had complete follow-up (2022-2025) and were included. Overall, 44.6% (78/175) were mRNA-positive (ASC-US 45.2%; LSIL 43.3%). For CIN2+, sensitivity was 63.4%, specificity 61.2%, PPV 33.3%, and NPV 84.5%; CIN2+ risk was 33.3% in mRNA-positive versus 15.5% in mRNA-negative women (RR 2.16, 95% CI 1.23-3.78). For CIN3+, risk was 14.1% versus 6.2%. Genotype-specific PPVs were highest for HPV33, HPV18, HPV16, and HPV31. In a referral simulation, mRNA-guided triage reduced baseline colposcopy referrals by 55% and decreased colposcopies per detected CIN2+ by ~30%, while 15 CIN2+ and 6 CIN3+ occurred in the mRNA-negative group and would be expected to be detected at 12-month follow-up among women with persistent HPV positivity. Genotype-aware HPV E6/E7 mRNA triage improves risk stratification and may increase screening efficiency.
