Knee extensor power predicts six-minute walk test performance in people with transfemoral amputations.
Article in PM & R : the journal of injury, function, and rehabilitation, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundLower-limb amputees have increased metabolic costs during walking that may be mitigated by maintaining quadriceps strength and power following amputation. However, there are no current studies investigating the relationship between thigh strength and walking performance in individuals with transfemoral amputation.
objectiveTo quantify the relationship between intact limb quadriceps strength in transfemoral amputees and six-minute walk test (6MWT) performance.
designDescriptive laboratory study.
settingLaboratory.
participantsEleven participants with unilateral transfemoral amputations from trauma or osteosarcoma (4 women/7 men, 46.21 ± 12.68 years old, 28.24 ± 20.57 years following amputation).
interventionsStrength and power testing on the intact limb followed by 6MWT with a flowmeter to measure oxygen uptake (VO
main outcome measuresStrength included mass-normalized peak torque, average torque, and average power. 6MWT measures included total distance traveled and VO
resultsPeak isokinetic knee extensor torque was correlated with total VO
conclusionsKnee extensor strength was correlated with performance on the 6MWT in individuals with unilateral transfemoral amputation. The strongest relationship was between isokinetic quadriceps power and distance traveled, which suggests that developing quadriceps power in the intact limb following amputation may be an important factor to reduce metabolic cost of walking and support a return to an active lifestyle.
