Hip Abductors Strength and Endurance in Individuals with Recent and Long-Standing Patellofemoral Pain.
Article in Journal of athletic training, 2025. 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
contextNumerous studies report deficits in hip muscle performance in individuals with patellofemoral pain (PFP). However, the exact stage at which these deficits emerge and the impact of symptom duration remain unclear.
objectiveTo compare hip abductor strength and endurance based on the presence or absence of PFP and its duration.
designCross-sectional study. PATIENTS OR OTHER
participants68 with PFP and 29 pain-free controls. MAIN OUTCOME MEASURE(S): We evaluated isometric maximal strength, isometric endurance, and dynamic endurance of hip abductors. Comparisons were made between participants with PFP and pain-free controls and among different PFP duration subgroups (< 12 months, ≥ 12 months, ≤ 6 months, > 24 months) and pain-free controls.
resultsHip abductor isometric strength (% body mass [BM]) was significantly lower in the PFP group (203.8 ± 46.8) and all PFP subgroups (< 12 months: 203.9 ± 57.0; > 12 months: 203.7 ± 42.2) (≤ 6 months: 205.1 ± 59.6; > 24 months: 207.7 ± 41.9), compared to pain-free controls (254.6 ± 60.3). However, no significant differences were found between PFP subgroups. There were also no significant differences in hip abductor isometric or dynamic endurance between PFP group and pain-free controls, or between PFP subgroups and pain free controls.
conclusionsHip abductors strength deficits emerge early in the course of PFP. However, further studies are needed to understand the observed lack of difference in endurance.
