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: To address clinical nursing challenges associated with postherpetic neuralgia(PHN), including recurrent pain shadow memory (PSM), refractory pain, and marked negative affect, this study assessed the effectiveness of a staged nursing pathway and identified key opportunities for cognitive-sensory-behavioral staged regulation, thereby providing a scientific foundation for improving nursing care for patients with PHN. Methods: A total of 100 patients diagnosed with PHN between July 2025 and April 2026 were enrolled and assigned to either a control group or an experimental group according to the admission period in a quasi-experimental design. The control group received routine nursing care, such as general nursing (e.g., vital signs, observation of the patient's condition, and medication administration). The observation group received a step-by-step nursing intervention, in addition to the control group's treatment, with three steps as follows: cognition correction (correcting irrational cognition about pain), sensory intervention (cold compress treatment combined with sensory desensitization), and behavioral counseling (desensitization language combined with behavior intervention). Results were evaluated with the Pain Shadow Behavior Identification Scale, the Numerical Rating Scale (NRS), and the Hospital Anxiety and Depression Scale (HADS). Data were analyzed using a t-test. Results: Baseline characteristics were comparable between the two groups (all Conclusion: The staged nursing pathway, which integrates sequential cognitive, sensory, and behavioral interventions, significantly reduced the recurrence of pain shadow memory, rapidly relieved pain, and improved anxiety and depression in patients with postherpetic neuralgia. This approach addresses the limitations of conventional nursing care and provides a feasible, effective, and evidence-based strategy for clinical practice.
