Evaluation of an e-self-management intervention (Happy Hands app) for hand osteoarthritis: Study protocol for a multicentre randomised controlled trial.
Article in Rheumatology international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05568875 (Happy Hands - an E-self-management Intervention for People With Hand Osteoarthritis), which is not on this map. Cited by 3 papers.
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
objectiveThis protocol paper describes the rationale and design of a randomised controlled trial (RCT) that aims to evaluate the (cost-)effectiveness of a 12 week e-self-management intervention (Happy Hands app) in people with hand osteoarthritis (HOA).
methodsIn this multicentre RCT, 376 people with HOA will be recruited from all four health regions in Norway. Consenting participants will be randomly allocated to either a control group receiving usual care or an intervention group receiving the Happy Hands app in addition to usual care. Primary outcome will be measured at 3-months follow-up as the proportion of participants classified as OMERACT-OARSI responders (a composite score comprising change in pain, function, and disease activity), analysed using logistic regression. Secondary outcomes, including pain, hand function, stiffness, quality-of-care, health-related quality-of-life, grip strength, adherence and healthcare costs will be measured at 3- and 6-months follow-up.
resultsRecruitment was initiated in November 2022 with a total of 386 participants recruited by August 2023, 194 in the intervention group and 192 in the control group. Data collection was completed in February 2024. DISCUSSION: To our knowledge, this is one of the first large-scale, multicentre RCTs assessing the (cost-)effectiveness of a self-management program delivered through a smartphone app for people with HOA. The results from this trial can enhance our understanding of the role technology can play in managing HOA.
