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
Generic medicines (GMs) are bioequivalent to brand-name medicines and more cost-effective, yet their use is limited. Gender-related factors may influence attitudes toward GMs, but data on older adults are scarce. This study aimed to explore sex and gender differences in knowledge and opinions about GMs among older patients and their caregivers. SurFE is a cross-sectional multicenter survey conducted in Italy (April-May 2023) that enrolled non-institutionalized individuals aged ≥ 65 years and their caregivers. Participants completed a questionnaire assessing knowledge, attitudes, and perceptions of GMs, and sociodemographic and health-related information. We collected data on gender-specific factors and, using a validated methodology, developed a composite gender score. Among the 471 participants (312 patients and 159 caregivers), no differences related to biological sex were observed. According to the gender score, patients with male gender characteristics were less likely to believe that generic medicines are made with lower-quality substances. Additionally, both female patients and male caregivers were more likely to consider GMs equivalent to brand-name medications. As for biological sex, ordinal regression analysis adjusted for sociodemographic and educational factors showed that female caregivers were significantly more likely to believe that GMs are produced with lower-quality substances (OR 2.06, 95% CI 1.01-4.21, p = 0.047). Also, focusing on gender, male patients were more likely to believe that GMs require more time to be effective (OR 1.89, 95% CI 1.06-3.35, p = 0.030), as well as female caregivers about the belief that GMs are produced with lower-quality substances (OR 2.25, 95% CI 0.33-1.60, p = 0.037), even if not confirmed in the adjusted model. No other significant associations emerged. Attitudes toward GMs may vary by gender, but not biological sex. However, this association was not independent of socio-cultural factors and should be explored in future longitudinal research to understand and address barriers to the use of GMs.
