Effect of an educational program on the knowledge, attitudes, and practices of hospital nurses regarding evidence-based practice: A quasi-experimental study.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPreparing nurses for evidence-based practice (EBP) requires developing their knowledge, skills, attitudes, and ability to apply evidence-based practice in clinical settings. This study assessed the effects of an educational program on hospital nurses' knowledge, attitudes, and practices regarding evidence-based practice.
methodsA quasi-experimental study with a control group and pre-post intervention assessments. The study was conducted among 116 hospital nurses in Kirkuk City, Iraq, selected using convenience sampling (58 in the intervention group and 58 in the control group). Nurses in the intervention group participated in an educational program on evidence-based practice. Data were collected at baseline and three months post-intervention using a structured self-administered questionnaire assessing knowledge, attitudes, and self-reported practice.
resultsNurses in the intervention group demonstrated statistically significant improvements in evidence-based practice knowledge, attitudes, and practices compared with baseline, while no significant changes were observed in the control group (p < 0.05). Repeated-measures ANOVA revealed a significant group × time interaction, with large effects on knowledge (η² = 0.85) and practice (η² = 0.69), and a moderate effect on attitudes toward evidence-based practice (η² = 0.13).
conclusionThe educational program was associated with significant improvements in nurses' EBP knowledge, attitudes, and self-reported practices. These findings suggest that structured EBP education can enhance nursing competencies and support the integration of evidence-based care into clinical practice.
