Bridging the Gap: Disparities in HPV Vaccine Uptake Between In-School and Out-of-School Girls Following a Demand Generation Intervention in Ethiopia: A Cross-Sectional Study.
Article in Vaccines, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDespite the availability of safe vaccines, Ethiopia's human papillomavirus (HPV) vaccine uptake remains suboptimal, particularly among out-of-school girls (OOSGs). This study examines the effect of multi-channel demand generation messages in two districts to determine which interventions most effectively improve uptake.
methodsA convergent mixed-methods design was employed across four districts in the Somali and South Ethiopia regions, with Jigjiga and Derashe serving as intervention sites and Gode and Kolango Zuria as controls. For the quantitative component, 950 sample households were recruited using cluster sampling. The qualitative inquiry involved 27 in-depth interviews (IDIs) and 16 focus group discussions (FGDs) within the intervention sites.
resultsA total of 950 caregivers and 1134 girls completed the survey. Awareness was significantly higher among caregivers (AOR: 4.42; 95% CI: (3.06, 6.39)) and girls (AOR: 7.63; 95% CI: (3.49, 16.67)) in intervention sites, as well as among in-school girls (AOR: 13.46; 95% CI: (4.09, 41.90)). The mean vaccination coverage reached 71%, with significantly higher rates in intervention sites (AOR: 4.07; 95% CI: (2.29, 7.23)) and among in-school girls (AOR: 47.16; 95% CI: (20.23, 109.9)). Interpersonal communication-via teachers, peers, community health workers and vehicle-mounted promotion-was more effective in influencing awareness, attitude and uptake. Barriers for OOSGs included limited access to vaccination sites, low campaign awareness, misconceptions and gender-related issues.
conclusionsAppropriate demand generation strategies effectively enhance HPV awareness and vaccine uptake, yet a significant equity gap remains, as only one-third of OOSGs received the vaccine compared with 85% of in-school girls. Targeted interventions are recommended for OOSGs focused on both access to service and context-specific demand creation to address this disparity.
