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: Dual contraception, the concurrent use of condoms and another effective method, is recommended for adolescents to prevent sexually transmitted infections (STIs) and unintended pregnancy. Identifying determinants of adolescent females' intention to use dual contraception is essential for promoting sexual and reproductive health. This study integrates the Health Belief Model and the Theory of Planned Behavior and to examine influencing factors. Objective: To identify determinants of intention to use dual contraception among female upper secondary school students in Thailand. Methods: A cross-sectional study was conducted among 407 female upper secondary school students in Nonthaburi Province, Thailand. Data were collected using a researcher-developed questionnaire between November 2025 and January 2026. Statistical analyses included descriptive statistics, Chi-square tests, Pearson's correlation coefficients, and multiple regression analysis. Statistical significance was set at p < 0.05. Results: Overall intention to use dual contraception was high ( Conclusion: Intention to use dual contraception among female students was high and was significantly associated with personal, cognitive, and psychosocial factors derived from the integrated theoretical framework. The findings can inform the development of targeted interventions, adolescent-friendly services, and collaborative strategies to enhance informed decision-making and promote dual-method contraceptive use among adolescents.
