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
purposeDigital-enhanced repetitive learning has been proposed as an effective strategy for improving dietary education among patients undergoing hemodialysis. This study examined the effects of a digital repetitive dietary education (DRDE) program on dietary knowledge, dietary self-care behaviors, and physiological indicators among hemodialysis patients residing in a rural area of South Korea.
methodsA quasi-experimental study with a nonequivalent control group and repeated measures was conducted. A total of 40 hemodialysis patients were recruited from a hemodialysis unit in a rural area of Chungcheongbuk-do, South Korea, and assigned to either an experimental group (n = 20) or a control group (n = 20). The experimental group participated in an 8-session DRDE program, whereas the control group received usual care. Data were analyzed using SPSS version 22.0 with the independent t-test, chi-square test, and 2 × 2 repeated-measures analysis of variance.
resultsParticipants in the experimental group demonstrated significantly greater improvements in dietary knowledge (F = 14.83, p = .001) and dietary self-care practice behaviors (F = 4.21, p = .048) compared with the control group. Significant improvements were also observed in selected physiological indicators, including interdialytic weight gain (F = 7.02, p = .012), serum potassium levels (F = 9.55, p = .004), and serum phosphorus levels (F = 4.62, p = .038).
conclusionThe DRDE program improved dietary knowledge, dietary self-care behaviors, and selected physiological outcomes among hemodialysis patients in rural areas. These findings suggest that the DRDE program is a practical and feasible nursing intervention for dietary management in rural hemodialysis settings with limited educational resources.
