Factors associated with pain after non-surgical treatment for trapeziometacarpal joint osteoarthritis.

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
introductionAlthough non-surgical treatment for trapeziometacarpal joint (TMJ) osteoarthritis (OA) reduces pain, outcomes vary substantially. This study investigated factors associated with pain at 3 months after starting non-surgical treatment for TMJ OA.
methodsThis secondary analysis from a previous randomized controlled trial included 113 patients (Eaton-Glickel stage ⩾2 TMJ OA) from 18 outpatient hand surgery clinics in The Netherlands, comprising specialized clinics, regional hospitals and one academic hospital. Participants were randomized to orthosis-only or orthosis + exercise groups. Both groups received a standardized custom-made thumb orthosis, and the combined group also received supervised hand therapy with a structured home exercise programme. The primary outcome was the Michigan Hand outcomes Questionnaire (MHQ) pain subscale at 3 months, which was modified so that higher scores indicated less pain. We used linear regression analysis to investigate the association of baseline pain, psychological factors, outcome expectations, adherence to therapy, perceived attention, patient experience with care, treatment frequency and changes in grip and pinch strength with MHQ pain.
resultsBetter MHQ pain score at baseline, higher baseline outcome expectations and improvement in grip strength after 3 months were associated with better pain outcomes. The MHQ pain baseline score had the strongest independent association.
conclusionBaseline pain severity, outcome expectations and grip strength are associated with pain at 3 months after the use of orthoses with or without exercise therapy for TMJ OA. LEVEL OF EVIDENCE: II.
