Maximizing impact: the power of early HPV vaccination for long-term protection-lessons from a systematic review and meta-regression analysis.
Synthesis in Journal of public health (Oxford, England), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
backgroundThis systematic review and meta-regression analysis assessed the impact of human papillomavirus 16/18 (HPV16/18)-AS04 vaccine (Cervarix®) on advanced cervical lesions, including grade 3 cervical intraepithelial neoplasia or worse (CIN3, CIN3+), or cervical cancer, highlighting age-at-vaccination-dependent vaccine efficacy and effectiveness.
methodsStudies reporting HPV16/18-AS04 vaccine efficacy or effectiveness were included with an intervention group receiving HPV16/18-AS04 vaccine and comparator group receiving placebo, another vaccine or being unvaccinated. Of 53 articles identified, nine were selected. Meta-analysis and meta-regression models with random effects and data-driven model selection determined vaccine effects (VEs) and impactful covariates.
resultsHPV16/18-AS04 vaccine effectively prevented advanced cervical premalignant lesions and cancer in adolescent girls and women vaccinated at 12-25 years. Combined randomized controlled trials and observational studies VEs on CIN3+ ranged between 76.78% (95% CI 28.15-92.49) for HPV16/18 and 56.19% (95% CI 24.76-74.49) irrespective of HPV type. Vaccine effectiveness was greatest in those vaccinated at the youngest ages.
conclusionsHPV16/18-AS04 vaccine provides long-term protection against cervical premalignant lesions and cervical cancer in both controlled and real-world settings, particularly when administered at younger ages. The evidence urges policymakers and the community to ensure HPV vaccination begins at the youngest recommended ages.
