Prevalence and Characteristics of Prehabilitation Utilization Among Older Medicare Beneficiaries Undergoing Elective Inpatient Lower Extremity Joint Replacement.
Article in Archives of physical medicine and rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesTo characterize trends and characteristics in individual receipt and facility delivery of preoperative rehabilitation ("prehabilitation") for lower extremity joint replacement (LEJR), and to characterize prehabilitation services delivered in terms of timing, frequency, duration, examining differences by preoperative frailty status and operative joint.
designRetrospective cohort study using administrative claims data.
settingInpatient facilities conducting elective LEJR surgery for Medicare beneficiaries in the United States.
participantsMedicare fee-for-service beneficiaries ages ≥65 years undergoing an incident elective inpatient hip or knee replacement between January 1, 2016, and December 31, 2019, identified in claims from a 20% random sample of Medicare beneficiaries.
interventionsPhysical or occupational therapy initiated within 30 days preceding LEJR surgery.
main outcome measures(1) Prevalence and characteristics of individual receipt of prehabilitation; (2) prevalence and characteristics of inpatient facility delivery of prehabilitation; and (3) prehabilitation attributes (timing, volume, setting).
resultsIn this sample of 196,690 older adult Medicare beneficiaries undergoing inpatient LEJR (mean age, 73y; 45.4% nonfrail; 37.5% hip), prehabilitation prevalence increased from 8.03% in 2016 to 11.14% in 2019. Stratifying by operative joint and frailty status, greatest increase was noted among nonfrail knee replacement patients (+3.64%). Most prehabilitation patients (77%) received a single visit, primarily in the outpatient physical therapy setting. Odds of receiving prehabilitation varied by patient race, sex, and financial and health characteristics. More than half (55.7%) of inpatient facilities delivered prehabilitation to at least one LEJR patient during the study period; odds of delivering prehabilitation varied by facility location, size, and financial characteristics.
conclusionsFindings demonstrate growth in LEJR prehabilitation utilization over time, supporting further investigation of why and how providers are implementing prehabilitation, what factors may affect patient access, and what strategies may maximize the utility of this spreading service delivery innovation.
