Association of Physical Therapy Care With Use of Intra-Articular Injections in People With Knee Osteoarthritis: A Real-World Cohort Study.
Article in Arthritis & rheumatology (Hoboken, N.J.), 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
objectiveThe objective of this study was to assess the relation of physical therapy (PT) timing, dose, and type with risk of future intra-articular therapy use in people with knee osteoarthritis (OA) who receive PT.
methodsWe used data from a deidentified claims database (Optum Labs Data Warehouse) from American adults with incident knee OA referred for PT within the first year of their knee OA diagnosis. We categorized people as having previously had intra-articular therapies or not. We examined the association of timing of PT initiation, number of PT sessions, and type of PT (predominantly active or passive) with intra-articular therapy use over a period of one year following the first year of diagnosis.
resultsOf the 67,245 individuals with knee OA (age 61.5 ± 11 years, 61% female, 10% Black, 6% Hispanic), 34,804 and 32,441 did and did not have prior intra-articular therapies, respectively. Among those who had prior intra-articular therapies, initiating PT at 9 to 12 months post diagnosis was associated with an adjusted risk ratio of 1.44 for future intra-articular therapy (95% confidence interval 1.35-1.55) compared with those who initiated within a month. For both groups, ≥13 PT sessions was associated with a 10% and 12% lower risk, respectively, compared with 1 to 5 sessions. Active PT was not related to lower risk compared to passive PT interventions.
conclusionInitiating PT earlier and more than 12 PT sessions were significantly associated with lower risk of future intra-articular therapy use in people with newly diagnosed knee OA.
