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
backgroundKnee osteoarthritis (OA) is the most common joint disorder of the knee, and its progression, influenced by multifactorial predisposing factors such as age, BMI, and physical activity, often results in significant limitations in day-to-day activities and deterioration of quality of life. Although the prevalence and predisposing factors of OA are well-documented globally, this study is distinct in its focus on the semi-urban population of Al Madam City, Sharjah. The unique socio-cultural and occupational characteristics of this community provide an opportunity to identify localized risk factors and their impact on OA prevalence, offering insights that can inform tailored healthcare strategies.
objectiveThe present study was conducted to estimate the prevalence of OA and its associated predisposing factors among the population of Al Madam, Sharjah.
methodsA community-based cross-sectional study was conducted to estimate the prevalence of knee OA in the population of Al Madam City, Sharjah. This study was conducted in twelve villages. 1300 participants were recruited through convenience sampling using a screening questionnaire survey to identify individuals with knee OA. The Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire was used, with an additional questionnaire consisting of questions related to its predisposing factors.
resultsThe prevalence of knee OA was 12.9% in Al-Madam City, Sharjah. Predisposing factors, such as age (χ
conclusionsThis study highlights that the prevalence of knee OA in Al Madam City is 12.9%, with significant associations observed between knee OA and factors such as age, sex, BMI, physical activity levels, education, and previous knee trauma. The findings underline the impact of the city's unique socio-cultural and occupational characteristics, such as high representation of labor-intensive jobs and limited leisure activity options, on the development of knee OA.
