Foot and ankle characteristics and dynamic knee valgus in individuals with patellofemoral osteoarthritis.
Trial report in Journal of foot and ankle research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
STUDY
designControlled laboratory study; cross-sectional design.
backgroundFoot and ankle characteristics and dynamic knee valgus differ in people with and without patellofemoral (PF) pain. However, it is unknown if these characteristics are evident in people with PF osteoarthritis (OA), compared to pain-free older adults.
objectivesTo compare foot and ankle mobility, foot posture and dynamic knee valgus, measured as the frontal plane projection angle (FPPA) during single-leg squatting, between individuals with and without PFOA.
methodsFifty-one participants with PFOA (66% women, mean ± SD age 57 ± 10 years, body mass index (BMI) 27 ± 6 kg/m
resultsThe PFOA group had less ankle dorsiflexion (odds ratio 6.7, 95% confidence interval 2.46-18.2), greater midfoot height mobility (5.2, 1.78-15.14) and width mobility (4.3, 1.33-14.39), and greater foot mobility magnitude (8.4, 2.32-30.69) than controls. There was no difference in FPPA (knee valgus angle) between groups (15, 0.63-377.99).
conclusionFoot and ankle characteristics were different in individuals with PFOA compared to control participants, however there was no difference in dynamic knee valgus during single leg squat. Clinical interventions to address greater foot mobility may be relevant for PFOA.
