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

backgroundRepairing diabetic foot wounds is challenging due to the high risk of necrosis associated with traditional skin flap techniques. This report introduces a novel separation-delayed flap technique and elaborates on its application in treating diabetic foot ulcers. CASE PRESENTATION: A 54-year-old Chinese male patient was diagnosed with diabetic foot ulceration, exhibiting a 4 cm × 3 cm full-thickness skin defect on the lateral aspect of the left ankle, with exposed fibular cortex and extension into the tibiotalar joint cavity. Upon admission, the wound underwent debridement followed by antibiotic-impregnated bone cement placement, and 3 weeks later, a conventional peroneal fascia-based flap was created, then isolated using a rubber membrane, and sutured in situ. Following 10 days of isolation, the flap was excised and transferred to the defect site for wound repair. Postoperatively, the skin flap survived entirely, the wound healed successfully, and the function of the skin flap returned to normal.

conclusionSeparation-delayed skin flap technique increases the survival rate of skin flaps by incrementally improving blood supply, making it an effective option for repairing diabetic foot wounds.
