Early postoperative walking recovery using a connected bodyweight-supported treadmill after hip fracture surgery in older patients: a retrospective cohort study (STAND-UP).

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
backgroundEarly mobilization to promote functional recovery and reduce the adverse effects of immobilization is one of the main goals of acute postoperative management of hip fracture (HF). The primary objective of this study was to assess, in usual care, the association between the use of a bodyweight-supported treadmill (BWST) and early postoperative walking recovery in older adults after hip fracture surgery. Secondary objectives were to evaluate delays to first sitting and first walking, daily walking distances, functional outcomes, length of stay, discharge destination, mortality, and the safety of BWST-based rehabilitation.
methodsWe conducted a retrospective cohort study in our perioperative geriatric care unit in Pitié-Salpêtrière hospital, Paris, enrolling all consecutive patients aged [Formula: see text] 70 years with HF who were admitted to the unit within 48 h after surgery from September 2021 to October 2023. In January 2023, the unit was equipped with a BWST, and patients received daily walking rehabilitation sessions exclusively using the BSWT instead of the previous conventional rehabilitation sessions.
resultsWe included 138 patients (mean [[Formula: see text]SD] age 87 [[Formula: see text] 6.6] years), 101 (73%) were female, the median age-adjusted Charlson Comorbidity Index (CCI) was 7 (interquartile range 5–9), and the median Activities of Daily Living (ADL) score was 5.5 (3.5-6.0); 48 (35%) received BWST training. On univariate analysis, BWST use was significantly associated with earlier first sitting (p = 0.03) and first walking (p < 0.001), greater walking distances at day 1 and day 6 (p < 0.001), greater difference in walking distance between day 1 and day 6 (p < 0.001), and reduced morphine use at discharge (p = 0.006) as compared with the standard rehabilitation care. After adjustment on CCI, ADL, and time between surgery and unit admission (multivariate mixed model), BWST rehabilitation was still positively associated with daily measured walking distances (β = 3.31, 95% CI [2.47;4.16]).
conclusionsThe use of a BWST was significantly associated with improved walking ability in the early postoperative care after HF surgery among older adults. Future interventional studies of larger cohorts are needed to confirm these findings.
