Multiple trajectories of life style indicators and their links to myopia in the middle school students: A five-year cohort 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
Little is known about the epidemiology of myopia-related behavior patterns among adolescents in economically developed regions of China, and their associations with myopia.This prospective cohort study included 1945 adolescents aged 12 to 17 years from 2019 to 2023. Lifestyle indicators (sleep time, moderate to vigorous physical activity (MVPA), outdoor time, screen time, extra-study time) were investigated by self-reported questionnaire annually, and trajectory groups were generated using group-based multi-trajectory models. The main outcome measures were noncycloplegic refractions and axial length (AL), corneal radius (CR).In the cohort of 1945 participants, we identified three lifestyle trajectory groups based on the distribution of lifestyle indicators. The "General" group accounted for 38.2%, exhibiting a longer sleep duration of about 8 h, approximately 3 days of MVPA ≥ 1 h weekly, daily outdoor time of at least 2 h, around 2 h of daily screen time, and weekly extra-study time of 0.5 h. The "Rapidly declining sleep time and prolonged extra-study time" (52.2%) group was characterized by a rapidly declining sleep duration and 2.5 h of weekly extra-study time. The "Persistently low MVPA and prolonged extra-study time" group (8.8%) demonstrated minimal physical activity, averaging only 0.6 days of MVPA ≥ 1 h weekly and 2 h of weekly extra-study time. Compared to "General", the "Rapidly declining sleep time and prolonged extra-study time" lifestyle was associated with myopia(OR:1.30; 95%CI = 1.01 to 1.67), rapid SE progression(OR = 1.35; 95%CI = 1.06 to 1.72), and higher myopia degree(OR = 1.10; 95%CI = 1.01 to 1.20); longer AL(β coefficient: 0.17; 95%CI = 0.05 to 0.29) and positive AL/CR ratio(β coefficient: 0.02; 95%CI = 0.01 to 0.03), but not associated with AL progression or AL/CR ratio progression. For middle school students in China, there were 3 different patterns of myopia-related behaviors. The lifestyle characterized by prolonged extra-study time and rapidly declining sleep time was associated with an elevated risk for myopia.
