Nurse-Led Educational Intervention Improves Self-Care Knowledge in Type 2 Diabetes: A Pre-Post Study Using the Diabetes Knowledge Questionnaire.

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
Objective Type 2 diabetes mellitus (T2DM) is a chronic, non-communicable disease that is becoming increasingly prevalent around the world, particularly in low- and middle-income countries. Patient education plays a critical role in promoting the self-care behaviours that are essential for glycemic control and preventing complications. The aim of this study was to evaluate the effectiveness of a nurse-led educational intervention in improving diabetes knowledge in adults with T2DM, as measured by the Diabetes Knowledge Questionnaire (DKQ-24). Materials and methods A quasi-experimental pre-post study was conducted at the Medical Care and Research Centre in Mérida, Yucatán, Mexico, from April to May 2025. Thirty adult patients with confirmed T2DM and no prior structured diabetes education participated in a three-session educational programme delivered by trained nurses. The DKQ-24 was administered before and after the intervention. Descriptive statistics and paired t-tests were used to analyse changes in total and domain-specific knowledge scores. A Shapiro-Wilk test confirmed normality, with a significance level of p < 0.05 applied. Results The mean DKQ-24 score increased significantly from 24.1 ± 5.8 to 26.4 ± 4.5 (p = 0.0039). Notable improvements were seen in items addressing misconceptions about special diets, wound care, and insulin production. The most significant knowledge gains occurred in the disease control and complications domain. Nine out of 24 items showed statistically significant improvement post-intervention. Conclusion A brief educational intervention led by nurses significantly improved patients' knowledge of diabetes, particularly by dispelling persistent myths. These findings highlight the important role of nurses in therapeutic education and support the incorporation of structured educational programmes into clinical diabetes care.
