Influencing factors of chronic pain after total knee replacement in osteoarthritis patients: a nomogram prediction model.
Article in American journal of translational research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesTo analyze the factors influencing chronic pain in patients with knee osteoarthritis after total knee replacement surgery (TKRS) and to construct a nomogram risk prediction model, providing an economically effective screening method for clinical use.
methodsThis retrospective study included 100 consecutive patients at the Jinan Central Hospital, with knee osteoarthritis who underwent TKRS from January 2023 to December 2023. Patients were divided into the observation group (n=55) and the control group (n=45) based on the presence of chronic pain. Logistic regression was performed to explore factors associated with chronic pain, including medical records, laboratory data, previous history, and independent clinical risk factors. The identified independent factors were then incorporated to construct a nomogram for chronic pain prediction.
resultsSix variables were identified as independent predictors of chronic pain after TKRS: age, BMI, diabetes, severity of preoperative pain, severity of postoperative acute pain, and postoperative wound infection (P<0.05). The area under the curve (AUC) of this nomogram was 0.836 [95% confidence interval (CI): 0.615-0.884], demonstrating good calibration and clinical practicability.
conclusionAge, BMI, diabetes, severity of preoperative pain, severity of postoperative acute pain, and postoperative wound infection are risk factors for chronic pain after TKRS. The predictive nomogram developed in this study shows good prediction ability and accuracy for chronic pain in patients with knee osteoarthritis after surgery.
