Application characteristics and clinical effectiveness of clinical finding staging in guiding non-surgical treatment of knee osteoarthritis involving 92 medical institutions.
Trial report in Journal of orthopaedic surgery and research, 2024. 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
backgroundAccumulating evidence suggests that the radiographic phenotypes of patients with knee osteoarthritis (KOA) often do not correlate with their clinical findings, which are the primary reason for seeking medical care. Therefore, at OARSI 2024, we proposed a clinical finding staging system-Chinese medicine staging (CMS)-to guide the treatment of KOA. However, the clinical effectiveness and application characteristics of CMS in guiding non-surgical treatment of KOA remain unclear.
methodsA total of 14,985 KOA patients were included in the study. Data from 13,983 patients were used to analyze the characteristics of CMS application, while 1465 patients were used to evaluate CMS-guided clinical effectiveness, and 152 patients were included in a comparative analysis of clinical effectiveness without CMS guidance. The demographic characteristics of the CMS-using population were examined, and the correlation between CMS and treatment modalities was analyzed to clarify CMS application characteristics. VAS and WOMAC scores were compared between the CMS-guided and non-CMS-guided groups both before treatment and at week 8 of treatment, using the minimal clinically significant difference as the benchmark.
resultsIn application characteristics, regarding nonsurgical treatments, an increase in the CMS led to a decrease in basic treatment and an increase in nonpharmacological and pharmacological treatments (P < 0.001). Regarding surgical treatments, no change in the proportion of surgical interventions was observed with worsening CMS (P > 0.05). In clinical effectiveness, at week 8 of treatment, VAS scores and WOMAC scores were significantly lower in CMS-guided group (VSA: 3.51; 95% CI, 3.42-3.60, Pain: 3.55; 95% CI, 3.40-3.70, Stiffness: 1.18; 95% CI, 1.11-1.25, Function: 12.57; 95% CI, 12.07-13.08, Total: 17.31; 95% CI, 16.63-17.99), which had a higher net difference than non-CMS-guided group (VSA: 3.30; 95% CI, 3.05-3.54, Pain: 3.14; 95% CI, 2.68-3.60, Stiffness: 0.95; 95% CI, 0.76-1.15, Function: 11.36; 95% CI, 9.80-12.91, Total: 15.45; 95% CI, 13.40-17.49). The net differences in CMS-guided group were all higher than in MCID.
conclusionCMS is consistent with the patient's clinical finding, is suitable for guiding non-surgical treatment of KOA and can achieve clinically significant therapeutic effects.
