EEG-Based Cortical Alterations in Patients Following Total Hip and Knee Arthroplasty Due to Osteoarthritis: Pre- and Post-Operative Assessment.
Article in Brain and behavior, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Quantitative electroencephalography (qEEG) has not yet been systematically applied to characterize cortical bioelectrical activity in patients undergoing total hip or knee arthroplasty. The aim of this study was to evaluate pre‑ to post‑operative changes in cortical activity and their relationship with functional outcomes after arthroplasty. Neuroplastic changes were examined in 81 patients with end‑stage osteoarthritis (33 hip, 48 knee) scheduled for primary total joint arthroplasty. All participants underwent clinical assessment one week before surgery and three months postoperatively using the Harris hip score (HHS), knee society score (KSS), and oxford knee score (OKS), together with full‑cap EEG recordings (19 electrodes) during resting state and stair‑climbing motor imagery. EEG analysis revealed a generalized increase in low alpha band power during rest after arthroplasty in both hip (n = 33) and knee (n = 48) patients, particularly over frontocentral and parietal regions (mean increases ∼1-3 µV
