How to score the wrist joint by ultrasound: exploration of the most sensitive joint assessment during follow-up of early or established rheumatoid arthritis.

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
backgroundWrist inflammation is common in patients with rheumatoid arthritis (RA), and thus there is room for debate on which joints to include in an ultrasound-based scoring of wrist synovitis in RA. This study aimed to identify the most treatment-sensitive major wrist joint, and assess potential differences between patients with early and established RA.
methodsThis post-hoc study analysed data from two independent cohorts, the ARCTIC trial (early RA) and the ULTRABIT study (established RA), with ultrasound-based semi-quantitative scoring of 36 joints and four tendons, including the radio-carpal (RC), inter-carpal (IC), and radio-ulnar (RU) joints of the wrists. Each joint was explored separately, along with the maximum score from two (RC, IC) or three (RC, IC, RU) joints, and the sum score of two (RC and IC, IC and RU, or RU and RC) or all three (RC, IC, and RU) joints. Sensitivity to change over 12 months for each wrist joint score was assessed using the standardised response mean (SRM).
resultsWe included 208 and 162 patients with early and established RA, respectively. Patients with established RA showed a higher prevalence of wrist joint synovitis at baseline and 12 months than those with early RA. The maximum score of the three wrist joints was most sensitive to change in early RA; SRMs of the greyscale (GS) and power Doppler (PD) were -0.82 and -0.73, respectively. The SRM of the sum score of the three wrist joints was highest in established RA, with SRMs for GS of -0.56 and PD of -0.54, which were comparable to SRMs of maximum score of the three wrist joints.
conclusionsTo assess changes in follow-up studies, ultrasound scoring should include all three major wrist joints in both early and established RA.
