Article in The Lancet regional health. Western Pacific, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01735006 (A Phase III Multicenter, Randomized, Double-Blind, Placebo), which is not on this map. Cited by 6 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.

Abstract
Background: A safe and highly efficacious Methods: In the Phase III clinical trial (NCT01735006), 7372 women were enrolled and randomly assigned to receive the HPV or control vaccine (hepatitis E vaccine). Women from 2 sites (Xinmi City and Fengning County; N = 1986) were invited to participate in the extension study. Cervical samples were collected for ThinPrep Pap tests and HPV DNA testing. Serum samples from participants in the immune persistent subcohort (N = 300) were collected for neutralising antibody testing. The co-primary outcomes were high-grade cervical, vulvar or vaginal lesions and persistent infection (over 6 months) associated with HPV 16/18 in the per-protocol population. Findings: A total of 1648 women participated in the extension study (806 from the vaccine group and 842 from the control group). Over a median 10.2-year follow-up, vaccine efficacy was 87.5% (95% CI 6.4-99.7) against high-grade cervical, vulvar or vaginal lesions (1 case in the vaccine group and 8 cases in the control group, Interpretation: The Funding: National Key Research and Development Program of China (2023YFC2307602), National Natural Science Foundation of China (823B2086, 82273640), Beijing Natural Science Foundation (L244091), and Fundamental Research Funds for the Central Universities (20720220005).
