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
objectiveTo understand menstrual experiences and perceptions of menstrual dignity among riverside adolescent girls in the Brazilian Amazon in order to support the participatory co-creation of an educational technology using Paulo Freire's research itinerary.
methodsTechnology development research, with a qualitative approach and participatory interface, grounded in Paulo Freire's research itinerary, composed of three stages: thematic investigation, coding/decoding and critical unveiling. The study was conducted in a public school located on Caratateua Island, Pará, Brazil, with the participation of 10 adolescents, and the investigation was operationalized through Culture Circles. Data were collected through audio recordings and field diary notes and analyzed using inductive thematic analysis aligned with Freirean stages, and the findings supported the participatory co-creation of an educational technology in the format of a comic book.
resultsThree main thematic categories emerged: (1) menstruation as emotional and daily life disruption, (2) silence and limited dialogue about menstrual experiences, and (3) sociocultural beliefs influencing menstrual care practices. These findings informed the development of a culturally contextualized comic book addressing menstrual knowledge, self-care, and menstrual dignity.
conclusionThe findings highlight the importance of culturally grounded educational approaches for menstrual health. The participatory co-creation process enabled the development of an educational resource aligned with adolescents' lived experiences and may support future health education strategies and research in menstrual health promotion.
