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

This study aimed to measure patellofemoral (PF) joint contact area for complete cycles of walking in both knees of individuals who had undergone unilateral anterior-cruciate-ligament reconstruction (ACLR) 6-15 months earlier. Computed tomography, magnetic resonance imaging, and biplane X-ray fluoroscopy were combined to determine PF contact area in the ACLR and uninjured contralateral knees of 15 individuals (26.3 ± 3.9 years) during level walking and downhill walking, and the results were compared to data for 10 healthy controls (29.8 ± 6.1 years). PF contact areas in ACLR and contralateral knees were comparable across the gait cycle for both activities, with total, lateral, and medial PF contact areas all increasing with knee flexion and reaching peak values of 560-595 mm
