Does cognitive behavioral education reduce pain and improve joint function in patients after total knee arthroplasty? A randomized controlled trial.
Trial report in International orthopaedics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07254923 (Three Brief Psychological Interventions for Acute Pain in Inpatients in Boyacá), which is not on this map. Cited by 27 papers, 4 of them syntheses that pooled it.
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.

Abstract
introductionCognitive behavioral therapy (CBT) is an effective treatment for reducing the pain of knee osteoarthritis (OA) and improving joint function. However, there are few studies on the effect of CBT on the pain severity after total knee arthroplasty (TKA). This study investigates the effectiveness of a CBT program on pain, knee function, quality of life, and pain catastrophizing in patients after TKA.
methodsThis was a randomized, parallel-group, controlled trial in which 100 patients with knee osteoarthritis (OA) prepared for TKA were randomly assigned to participate in CBT or usual care group. Evaluation outcomes include Visual Analogue Scale (VAS), Pain Catastrophizing Scale (PCS), Oxford Knee Score (OKS), Knee Range of Motion (ROM), EuroQol Five-Dimensional (EQ-5D), and Hospital for Special Surgery (HSS) Knee Rating Scale before and after surgery.
resultsWe found that patients in the CBT group had a lower pain during activity from the fifth day (p = 0.003) to the third month (p = 0.019) after TKA. At the 12th month, the mean VAS score during activity in the CBT and usual care groups decreased from 4.5 to 0.8 and from 4.6 to 0.9, respectively, and there is no significant difference between the two groups. The PCS scores of patients in the CBT group were lower than those in the usual care group at 1st (p = 0.014) and 3rd months (p = 0.027) after surgery. No statistically significantly differences between the two groups in pain during rest, knee ROM, EQ-5D, OKS, and HSS.
conclusionsThe CBT program was superior to usual care in reducing post-operative pain during activity from the fifth day to the third month and pain catastrophing in the first three months after TKA but has no statistically significantly differences in pain during rest, knee ROM, EQ-5D, OKS, and HSS.
