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

Simultaneous bilateral patellar tendon rupture is an exceedingly rare injury, often linked to systemic comorbidities. This report presents the case of a 31-year-old active male with a history of hypothyroidism, asthma, and chronic anabolic steroid use who sustained bilateral ruptures while running. He underwent urgent surgical repair using intratendinous sutures augmented with a double-bundle ipsilateral gracilis autograft. Postoperatively, a structured rehabilitation protocol was followed. At the 1-year follow-up, the patient achieved an excellent clinical outcome, with an IKDC score of 92.3 and a Kujala score of 95, returning to all pre-injury high-demand physical activities without limitation. This case highlights the efficacy of early surgical repair with gracilis autograft augmentation for restoring high-level knee function in patients with significant risk factors for tendon injury.
