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
Background: Human papillomavirus (HPV) vaccination is a cornerstone of global strategies to prevent HPV-associated malignancies; however, uncertainties persist regarding its long-term efficacy, immunogenicity, and safety across populations, vaccine formulations, and dosing schedules. We conducted a comprehensive systematic review and meta-analysis to evaluate the clinical and immunological effectiveness of prophylactic HPV vaccines. Methods: This study followed PRISMA guidelines and was registered in PROSPERO (CRD420251050526). Randomized controlled trials (RCTs) were identified through comprehensive searches of six major databases. Risk of bias was assessed using the RoB 2 tool. Meta-analyses were performed using random- or fixed-effects models as appropriate. Subgroup and meta-regression analyses explored the effects of age, sex, vaccine type, dosing regimen, and HIV status. Certainty of evidence was appraised using the GRADE framework. Results: A total of 145 RCTs were included. HPV vaccination significantly reduced cervical intraepithelial neoplasia grade 1 (RR = 0.15, 95% CI: 0.09-0.24), grade 2 (0.20, 0.13-0.30), and grade 3 (0.48, 0.23-0.98). Persistent HPV16/18 infections were reduced by 84% (0.16, 0.12-0.21), and incident infections by 75% (0.25, 0.19-0.34). Immunogenicity analyses demonstrated robust antibody responses, with fold increases of 3.09 for HPV16, 3.10 for HPV18, 3.48 for HPV6, and 3.37 for HPV11. Tissue-resident CD4 Conclusion: Prophylactic HPV vaccination provides strong protection against HPV infections and precancerous lesions and induces robust humoral immunity with a favorable safety profile. The nonavalent vaccine, particularly when administered in a three-dose (0/1/6) regimen, offers the most comprehensive protection. These findings support the expansion of gender-neutral vaccination programs to maximize population-level cancer prevention.
