1 · What the graph read from it

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.

2 · The registry

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

purposeKnee osteoarthritis (OA) is symptomatic, especially in terms of motion during activities of daily living. The infrapatellar fat pad (IFP) has a buffering function, owing to morphological changes within the knee joint, whereas poor morphological change in the anterior space of the IFP is often observed in symptomatic knee OA. This study aimed to investigate the correlation between morphological changes in the anterior space of the IFP during walking and symptoms in patients with knee OA.

methodsTwenty-six patients with knee OA (OA group) and 11 healthy volunteers (control group) participated in this study. Ultrasonography revealed the IFP thickness in the anterior space during static and dynamic evaluations in the supine and walking positions. The waveform of the IFP during walking was constructed with a continuance value of the IFP in video mode. Moreover, it identified the difference in IFP between maximum and minimum values on the waveform as morphological change in IFP (ΔIFP). A three-dimensional motion analysis system was used to calculate the kinetics and kinematics of walking. The OA group underwent clinical evaluation using the Knee Injury and Osteoarthritis Outcome Score (KOOS).

resultsΔIFP in the OA group was smaller than that in the control group, whereas there was no significant difference in supine IFP thickness. Moreover, there was a significant positive correlation between ΔIFP and KOOS-pain in the knee OA group, but not in terms of other parameters of IFP, kinetics, and kinematics.

conclusionsPatients with symptomatic knee OA exhibit restricted morphological change in IFP during walking.
