Comparison of the Quadriceps Muscle Thickness and Function between Patients with Patellofemoral Pain Syndrome and Healthy Subjects using Ultrasonography: An Observational 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
Objectives: To compare the thickness and function of the quadriceps muscle in subjects with and without patellofemoral pain syndrome (PFPS) by ultrasonography. Methods: Patients diagnosed with PFPS were included in the study. To measure the thickness of the rectus femoris (RF), vastus medialis longus and oblique (VML, VMO), vastus lateralis (VL) and vastus intermedius (VI), the ultrasonography was employed in rest and normal contraction modes and also the % rest-thickness normal as muscle function. For between-groups comparisons, the independent sample t-test was utilized. Results: Sixty subjects (30 PFPS and 30 healthy) participated in this study. There were no significant differences between two groups with respect to demographic characteristics. No significant differences were observed between two groups regarding RF (P=0.07), VMO (P=0.38), VL (P=0.40) and VI (P=0.55) at rest. However, the rest thickness of VML (P=0.01) was significant between PFPS and healthy groups. No significant differences were found between two groups regarding RF (P=0.14), VML (P=0.68), VMO (P=0.11), VL (P=0.65), and VI (P=0.07) in contraction state. However, % rest-thickness normal were significant between groups for VML (P=0.03) and VMO (P=0.02) and were not significant for RF (P=0.56), VL (P=0.14) and VI (P=0.08). Conclusion: In all parts of the quadriceps, % rest-thickness normal, as an indicator of its function, have been decreased in patients with PFPS. In patients with PFPF, ultrasonography should be cautiously used for muscle thickness comparisons.
