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
Human papillomavirus (HPV) vaccination remains a critical public health strategy for preventing HPV-related diseases; however, vaccination uptake continues to be influenced by multiple psychological and contextual factors. This study examines the determinants of willingness to vaccinate (WTV) and vaccination behavior (VB) by integrating constructs from the Health Belief Model, Protection Motivation Theory, and the 3Cs framework, including perceived severity (PS), perceived vulnerability (PV), complacency (COM), and vaccine confidence (CONF). A cross-sectional survey design was employed to collect data on individuals' perceptions, attitudes, willingness to vaccinate, and vaccination behavior. The study tested the direct effects of PS, PV, COM, and CONF on WTV, the mediating role of WTV in predicting VB, and the moderating effects of HPV vaccine recommendations and HPV-related information sources on the proposed relationships. The findings demonstrate that perceived severity, perceived vulnerability, and vaccine confidence positively influence willingness to vaccinate, whereas complacency negatively affects willingness. WTV significantly mediates the relationships between PS, PV, COM, CONF, and vaccination behavior. Moderation analysis revealed limited but significant moderating effects: HPV vaccine recommendations and HPV-related information sources strengthened selected relationships within the model, while several proposed moderation effects were not statistically supported. This study provides an integrated framework for understanding HPV vaccination behavior by combining cognitive, motivational, and contextual determinants. The findings highlight the importance of enhancing risk awareness, reducing complacency, strengthening vaccine confidence, and leveraging effective recommendations and information channels to improve HPV vaccine uptake. These insights offer practical implications for designing targeted public health communication and vaccination promotion strategies.
