Effectiveness of mobile application versus intranet-based posting for pressure ulcer education in nurses: a randomised controlled trial.
Article in BMC nursing, 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
backgroundPressure ulcers are major patient safety concerns, and bedside nurses' competencies are central to prevention. Given nurses' workload in clinical settings, digital education delivery through mobile apps or intranet may be effective. However, direct comparisons between these modalities remain limited. This study aimed to compare mobile application and intranet-based pressure ulcer education for staff nurses and examine effects on knowledge, attitude, and self-efficacy.
methodsThis randomised controlled trial was conducted in an inpatient nursing department at a general hospital in Seoul, South Korea. Sixty-three ward nurses with at least one year of clinical experience were randomised to the mobile app group (n = 32) or the intranet group (n = 31). One participant assigned to the intranet group did not initiate the allocated education and did not complete the post-intervention assessment. Thus, the complete-case outcome analysis included 62 participants. A four-week pressure ulcer management programme was delivered via mobile app or weekly intranet postings. Knowledge, attitude, and self-efficacy were measured pre- and post-intervention. Difference-in-differences regression analysis assessed group-by-time effects.
resultsBaseline characteristics and baseline outcome scores were similar between groups. The group-by-time interaction terms were not statistically significant for knowledge (β = 0.31, p = .677), attitude (β = -0.64, p = .554), or self-efficacy (β = 0.57, p = .559), indicating no evidence that pre- to post-intervention changes differed between the mobile app and intranet groups. Descriptively, mean scores increased from baseline to post-intervention in both groups.
conclusionsMobile app-based pressure ulcer education did not demonstrate a statistically significant advantage over intranet-based delivery among experienced staff nurses. Mean scores increased from baseline to post-intervention in both groups, suggesting that structured digital access to the same educational content may support pressure ulcer continuing education in clinical nursing settings.
