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
Introduction: Health-related decision-making is influenced by a complex interplay of cognitive, emotional, and personality-related factors. Psychological characteristics such as distress, personality traits, and maladaptive cognitive patterns play a central role in shaping how individuals perceive medical information, engage with healthcare systems, and adhere to health-related recommendations. Understanding these determinants is essential for clarifying individual differences in healthcare behaviors and for informing effective interventions in clinical and public health contexts. The present research introduces the Psychological Factors in Healthcare Behavior Questionnaire (PF-HBQ), a novel instrument designed to assess psychological dimensions relevant to healthcare-related decision-making. Overall, the PF-HBQ was developed to capture individual differences in psychological functioning that may influence attitudes and behaviors in medical contexts. Methods: The research was conducted through two studies. In Study 1, the psychometric properties of the questionnaire were evaluated on a large sample of individuals (N=472, 149 males, aged 18-86 years) by performing confirmatory and exploratory factor analysis, assessing test-retest reliability and convergent and divergent validity. In Study 2, differences in psychological factors between vaccine hesitant vs. non-hesitant individuals were explored in a further sample of participants (N=192, 47 males aged 18-71 years). Results: The results showed that the PF-HBQ questionnaire is a reliable and comprehensive tool for assessing 9 psychological factors (Suspiciousness, General Distress, Extraversion, Openness, Procrastination, Depressive Symptoms, Post-Traumatic Symptoms, Obsessive-Compulsive Traits, Emotional Stability) relevant to healthcare decision-making and shaping health-related attitudes and behaviors, including vaccination-related decision-making. Discussion: These findings may contribute to a deeper understanding of psychological influences on healthcare engagement and support the development of tailored public health strategies.
