Reduced walking speed at discharge predicts mortality after clinical osteoporotic vertebral fracture: A retrospective cohort study.

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
This study investigated how walking speed affects survival in patients with clinical osteoporotic vertebral fractures. A walking speed below 0.71 m/sec was associated with increased mortality. Walking speed may serve as a simple yet powerful prognostic indicator, highlighting the importance of mobility preservation in fracture management. PURPOSE: The number of patients with fractures caused by osteoporosis has increased with the increasing proportion of aging adults in recent years. Osteoporotic vertebral fractures (OVFs) are associated with poor prognosis. Although several reports on the life expectancy of patients with OVFs exist, it is unclear how walking speed affects the life expectancy of patients with clinical OVFs. This study investigated the relationship between walking speed and life expectancy after injury in patients with clinical OVFs.
methodsA total of 104 patients with new clinical OVFs were conservatively treated with a trunk cast from 2015 to 2017. Lumbar spine and femur bone mineral density (BMD), the Geriatric Nutritional Risk Index (GNRI), walking speed, and spinopelvic parameters were measured. We compared the deceased and survival groups and examined the risk factors influencing survival.
resultsAmong the 104 patients included in the study, 67 were women; the median age was 82 years, and the median observation period was 1168 days. Thirty-two patients died during the observation period. The deceased group had a lower GNRI and a slower walking speed at discharge. In addition, imaging revealed more local kyphosis and more calcification of vessels in the deceased group. The risk of death increased when the walking speed after the OVF was less than 0.71 m/sec.
conclusionA walking speed of 0.71 m/sec or slower was associated with poor prognosis after clinical vertebral fracture. Nutritional management, kyphotic deformity prevention, and walking speed maintenance are essential for vertebral fracture treatment.
