The effects of the forgetting curve in the training of knee arthroplasty surgical instrument nurses: a pilot randomized 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
objectiveThis study aimed to compare the conventional review teaching method with the forgetting curve-based teaching method in the training of novice knee replacement surgical instrument nurses.
methodFrom April 2021 to April 2024, 30 new surgical instrument nurses were enrolled and randomly divided into 2 groups (n = 15). The control group received the conventional review teaching method, while the intervention group received the forgetting curve-based teaching method, which included three reviews of knowledge and skills at 24 h, 7 days, and 30 days. The performance of the two groups was compared in terms of clinical training assessments, the satisfaction of surgeons with the cooperation of new operating room nurses, and the satisfaction of new operating room nurses with teaching.
resultCompared to before training, the clinical training assessment scores of both groups increased 1 day (from 64.33 ± 7.17 to 90.33 ± 7.18 in the intervention group and from 64.60 ± 7.31 to 85.40 ± 8.37 in the control group) and 1 month (from 64.33 ± 7.17 to 89.86 ± 7.19 in the intervention group and from 64.60 ± 7.31 to 75.33 ± 7.91 in the control group) after training (P < 0.05). In the experimental group, there was no significant difference in the clinical training assessment scores 1 day and 1 month (90.33 ± 7.18 vs. 89.86 ± 7.19, respectively) after training (P > 0.05), while the control group showed a decrease in the clinical training assessment score 1 month after training compared to 1 day after training (85.40 ± 8.37 vs. 75.33 ± 7.91) (P < 0.05). At 1 month after training, clinical training assessment scores were higher in the experimental group than in the control group (89.86 ± 7.19 vs. 75.33 ± 7.91). Compared to the control group, the experimental group exhibited a higher surgeon satisfaction score (91.44 ± 7.68 vs. 85.10 ± 8.54) (P < 0.05) and surgical instrument nurse satisfaction scores after applying the forgetting learning curve-based teaching method (P < 0.05).
conclusionIn this study, the incorporation of the forgetting curve into educational programs improved the clinical training assessment score and satisfaction score of surgical instrument nurses and increased the satisfaction score of surgeons for knee transplantation surgery.
