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: This study examined the relationship between work-related physical workload and knee cartilage loss using magnetic resonance imaging (MRI) among farmers and fishers in the Republic of Korea. Methods: Bilateral knee MRI and questionnaire data from 545 farmers and 204 fishers aged 40-79 years were analyzed. Cartilage damage was evaluated using the MRI Osteoarthritis Knee Score (MOAKS). Mean cartilage loss scores were compared by sex, age, and body mass index (BMI). Analysis of covariance (ANCOVA) was used to assess associations of cumulative squatting work time (CSWT, hours) and cumulative lifting work time (CLWT, hours) with cartilage loss, adjusting for age and BMI, and stratified by sex. Results: Age was the most significant factor associated with cartilage loss, whereas BMI was not. In women, CSWT was significantly associated with medial cartilage loss in the tibiofemoral (TF) joint after adjusting for age and BMI (right: Conclusion: Among Korean farmers and fishers, cumulative squatting and lifting workloads were associated with knee cartilage damage in a compartment- and sex-specific manner.
