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
Background: Repair of chronic quadriceps tendon ruptures has high rates of rerupture and extensor lag. Dermal allograft augmentation of tendon repairs has shown to increase repair strength and healing rates. Indications: We supplement primary quadriceps repair with dermal allograft augmentation in cases where tissue degeneration has occurred secondary to a subacute or chronic nature to help facilitate incorporation of the tendon tissue to bone. Technique Description: The patient is a 30-year-old man who presented with a chronic quadriceps tendon rupture. Intraoperatively, the quadriceps tendon excursion was found to be adequate for primary repair. Two sets of fiber tapes were used to secure the quad tendon with Krackow stitches and were loaded onto 2 suture anchors and placed in the proximal pole of the patella. The medial and lateral anchor sutures and loops were fed through the medial and lateral aspects of the dermal allograft, respectively. To secure the dermal allograft, the stay suture from the medial anchor was passed through the knotless mechanism of the lateral anchor and vice versa. This allowed for a broad area of direct compression of the allograft against the site of repair at the tendon bone interface between the 2 anchors. Results: Chronic quadriceps tendon repairs are known to have poor outcomes with up to 10% rerupture rates and extensor lag of more than 5° in 22% of cases. Several studies have shown that dermal allograft augmentation of tendon repairs increases pullout strength, maximum load to failure, and healing rates. Discussion/Conclusion: Dermal allograft augmentations of chronic quadriceps rupture repair provide a scaffolding for cellular migration and collagen formation to help solidify the bone-tendon interface and may prove useful in addressing the reported high rates of rerupture and extensor lag.
