Proportion of Acceptable Symptom State Nearly Tripled With Improvements in Patient-Reported Outcomes for All Symptom State Subgroups: A Registry Study of More Than 15,000 Patients With Osteoarthritis in Digital Education and Exercise Therapy.
Observational study in Arthritis care & research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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.
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
objectiveThis study investigated trajectories of patient acceptable symptom state (PASS) among participants of digital education and exercise therapy for knee and hip osteoarthritis.
methodsA longitudinal observational study among individuals aged at least 40 years who participated in the digital program. Participants completed PASS (yes/no) at enrollment and at least one follow-up during 1 year after enrollment (N = 15,253). Group-based trajectory modeling was used to identify groups with distinct PASS trajectories. We used multinomial logistic regression and linear random intercept models to explore predictors and compare changes in patient-reported outcome measures (PROMs) across trajectory subgroups.
resultsThe proportion of participants reporting acceptable symptom state rose from 17.4% (95% confidence interval [CI] 16.8%-18.1%) at enrollment to 42.4% (95% CI 41.6%-43.1%) and 48.9% (95% CI 47.5%-50.2%) at 3- and 12-month follow-ups, respectively. We identified four PASS trajectories: (1) "persistently not achieving PASS" (PNAP) (45.1%), (2) "early sustained PASS" (ESP) (34.8%), (3) "gradually increasing satisfaction" (GIS) (10.8%), and (4) "early PASS, later unacceptable PASS" (9.3%). Among baseline variables, female sex, older age, nonmetropolitan residence, lower education, knee osteoarthritis, fear of movement, no walking difficulties, no wish for surgery, and better PROMs were generally associated with higher odds of following trajectories other than the PNAP. All trajectories experienced improvements in PROMs, with generally larger improvements in the ESP and GIS groups than the other two groups.
conclusionThe percentage of participants achieving PASS almost tripled at 12 months. Improvements in PROMs across all PASS trajectories highlights the importance of distinction between "feeling better" and "feeling good."
