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
Objectives: To assess the relationship between knowledge regarding diabetes and medication adherence among diabetic patients. Methodology: A cross-sectional study was conducted at the diabetes, primary care and internal medicine clinics in King Khalid University Hospital, Riyadh, Saudi Arabia, over a period of six months (July 2024 - December 2024). Data were collected using an electronic questionnaire incorporating two validated scales: the simplified diabetes knowledge scale and Morisky Medication Adherence Scale. Analysis was performed using SPSS version 26.0, applying the Chi-square test for categorical variables and Spearman's rank correlation to assess the relationship between knowledge and adherence. Statistical significance was set at p ≤ 0.05, with 95% confidence intervals. Results: The mean age was 51.1± 16.5 years, with 39.6% over 60. Males constituted 52.9% of the sample, and 66.9% were married. The majority (61.5%) had Type-II diabetes and good glycemic control (HbA1c < 8) (51.1%). A weak correlation was found between diabetes knowledge and medication adherence (r = 0.118, p = 0.115). Diabetes knowledge was good in 50.7% with a positive correlation with educational attainment (p = 0.000) and employment status (p = 0.042). Medication adherence was low in 32%, medium in 36.7% and high in 31.3%. Higher adherence rates were observed in patients with Type-II diabetes (p = 0.010) and those who have good glycemic control (p = 0.006). Conclusion: Although diabetes knowledge is important for promoting adherence, it is not sufficiently effective on its own to guarantee compliance. Targeted educational interventions, particularly for those with lower education, unemployment, or a recent diagnosis, may enhance adherence, improve outcomes and reduce the burden of diabetes in Saudi Arabia.
