Association Between Pain Catastrophising and Functional Limitation in Patients With Knee Osteoarthritis:
Article in Sultan Qaboos University medical journal, 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
Objectives: Knee osteoarthritis (KOA) is a common reason for consultation in rehabilitation settings, responsible for pain and restricted autonomy. This study aimed to determine the association between catastrophising and functional limitation in patients followed for KOA in physical medicine and rehabilitation. Methods: This cross-sectional analytical study was conducted from June to August 2025 at the Department of Physical Medicine and Functional Rehabilitation in Taher Sfar University Hospital, Mahdia, Tunisia. Demographic data, the history of KOA as well as the radiographic stage of Kellgren and Lawrence were collected from patients with KOA. Functional impairment was assessed by the Lequesne knee index and catastrophising was assessed by the Pain Catastrophizing Scale (PCS) questionnaire in its Arabic translated and validated version. Results: A total of 90 patients were included with a mean age of 58.76 ± 9.09 years. Most were women (88.9%) and obesity was present in 44.4% of patients. KOA was bilateral in 73.3% of cases. The mean on 100 of the VAS pain at rest was 29.18 ± 19.69 and at walk 57.14 ± 15.81. The mean Lequesne score in the population was 11.33 ± 3.53 and that of the PCS was 23.91 ± 11.28. Significant factors associated with a high level of catastrophizing were the level of education ( Conclusion: These findings demonstrated an association between catastrophising and functional limitation in KOA. Evaluating pain catastrophisation during the follow-up of these patients, may guide and personalise therapeutic strategies, such as cognitive-behavioural approaches, pain management and rehabilitation according to each patient';s needs.
