The impact of medical expert-led sex education on sexual health knowledge among Japanese junior high school students: a quantitative study.

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
objectiveThis study aimed to evaluate the impact of a sex education lecture led by medical professionals on junior high school students' knowledge and attitudes regarding oral contraceptives (OCs), contraception, cervical cancer, and human papillomavirus (HPV) vaccination. MATERIALS AND
methodsThe study received approval from Nippon Medical School Hospital's Ethics Committee. Thirty-seven high schools participated in the lecture, which featured a 1-h comprehensive lecture delivered by a gynecologist. Questionnaires were administered both before and after the lecture.
resultsA total of 5,833 and 5,383 students responded to the questionnaires before and after the lecture, respectively. Female students were more likely to seek information from teachers and parents, while male students relied on friends or had limited knowledge. Postlecture, awareness of OCs increased, with more students recognizing their benefits beyond contraception, such as relieving menstrual cramps. There was also a marked improvement in understanding contraceptive methods. Knowledge of cervical cancer and HPV saw a significant rise, with more correct responses reported. Additionally, the lecture prompted a greater willingness among students to receive the HPV vaccine.
conclusionsThe findings indicate that sex education delivered by gynecologists led to significant gains in knowledge and awareness and may have contributed to more positive attitudes toward sexual and reproductive health among male and female students. These results underscore the potential benefits of involving medical experts in sex education to enhance its impact on adolescents in Japan.
