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

Background: Recently, the quadriceps tendon (QT) has gained attention as a graft material for anterior cruciate ligament (ACL) reconstruction. However, no study has yet evaluated the maturation process of the reconstructed ACL using QT grafts. Magnetic resonance imaging (MRI)-Ultra Short Echo time (UTE) T2∗ mapping is a precise technique for quantifying tissue states in tendons and ligaments. This study aimed to prospectively observe trends in UTE-T2∗ values for the intra-articular and intra-osseous regions of the reconstructed ACL from 6 to 12 months following ACL reconstruction using MRI-UTE-T2∗ mapping and to assess graft maturation of the reconstructed ACL with QT grafts. Methods: This study enrolled 10 patients (five males and five females). For each patient, UTE-T2∗ values were measured at 6, 9, and 12 months postoperatively. A two-way mixed ANOVA was performed with time (6, 9, and 12 months) as a within-subjects factor and location (intra-articular, tibial intra-osseous, and femoral intra-osseous) as a between-subjects factor. Results: A significant main effect of time was observed (F (2,54) = 38.162, p < 0.001), with UTE-T2∗ values decreasing as postoperative time progressed. Additionally, a significant main effect of measurement location was identified (F (2,27) = 95.853, p < 0.001), with intra-articular UTE-T2∗ values being significantly higher than those in the tibial and femoral intra-osseous regions (p < 0.001). Conclusion: Quantitative assessment using MRI-UTE-T2∗ mapping following ACL reconstruction with QT grafts demonstrated that graft maturation progressed more rapidly in the intra-osseous region compared to the intra-articular region.
