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
Musculoskeletal discomfort among children carrying school bags is an increasingly significant problem. This study sought to determine the prevalence and risk factors of musculoskeletal discomfort among Thai primary school students who carry excessively heavy school bags. We conducted cross-sectional descriptive research involving 489 primary school students (ages 7-12). We utilized the standardized Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) to assess discomfort in various body regions. Measurements included student weight, school bag weight, and the angles of neck and trunk inclination. Logistic regression was used to analyze factors influencing musculoskeletal discomfort. The results showed that the majority of students had musculoskeletal discomfort (66.67%). The average relative weight of the school bags was 17.46 ± 6.02%. Significant risk factors for musculoskeletal discomfort included being female (AOR = 1.87, 95% CI = 1.12-3.10), being in grades 1-3 (AOR = 0.221, 95% CI = 0.05-0.91), carrying bags for more than 20 min per day (AOR = 28.87, 95% CI = 8.93-93.31), not storing books at school (AOR = 2.06, 95% CI = 1.07-3.95), and carrying a school bag weighing > 10% of the student's body weight (AOR = 65.46, 95% CI = 14.73-290.93). Additionally, neck and trunk inclinations > 20 degrees were associated with increased discomfort (AOR = 3.25, 95% CI = 1.89-5.57; AOR = 3.26, 95% CI = 1.58-6.70). The prevalence of musculoskeletal discomfort was higher in Thai primary school students. Female, Grades 1-3, carrying bags exceeding 20 min/day, carrying a school bag weighing > 10% of the student's body weight, and neck and trunk inclinations > 20 degrees were predictor variables for musculoskeletal discomfort. Thus, collaborative efforts from educational institutions, educators, parents, and students are essential in addressing this issue.
