The Impact of Patient-Controlled Analgesia Combined with Self-Management Training on Pain Modulation in Diabetic Patients with Chronic Knee Pain.

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
Background: Chronic knee osteoarthritis is a debilitating condition characterized by persistent knee pain and functional impairment. This study aimed to evaluate the impact of Patient-Controlled Analgesia (PCA) combined with self-management training on postoperative pain management in diabetic and non-diabetic patients with chronic knee pain. Methods: We conducted a cohort study of 100 patients (40 diabetic, 60 non-diabetic) undergoing knee replacement surgery. Participants were assigned to receive either PCA with self-management training or standard care. Pain was assessed using VAS scores, and self-management ability was evaluated with a preliminary DSSMET. The impact of PCA and diabetes status on these outcomes was evaluated using multivariate regression models (multiple linear and logistic), which adjusted for confounding variables. All analyses were performed in SPSS 25.0 with statistical significance set at p < 0.05. Results: The results showed that baseline characteristics showed no age difference between groups, but diabetic patients had shorter discharge times and higher blood glucose levels (P<0.001). VAS scores indicated higher pain in diabetic patients (P<0.001), with significant pain reduction in the PCA subgroup (P=0.036). The DSSMET showed good reliability (Cronbach's α =0.87) and validity (four-factor structure). Furthermore, PCA was associated with effective pain relief, with this effect being most pronounced in diabetic patients. Conclusion: This study developed a preliminary tool to evaluate self-management ability in chronic knee pain patients and investigated the effect of PCA combined with self-management training on pain relief. The results suggest that this combined intervention may effectively relieve pain, particularly in diabetic patients. Furthermore, high patient engagement and adherence indicate good acceptability of the combined PCA and self-management protocol.
