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

backgroundThe face, with its distinct subunits, demands particularly high aesthetic standards for defect reconstruction. Although traditional hatchet flaps are commonly used, they are limited by a constrained rotation arc and susceptibility to dog-ear deformities, compromising aesthetic outcomes. This study introduces and investigates a novel free-style perforator-based hatchet flap technique designed to overcome these limitations and enhance aesthetic outcomes. PATIENTS AND

methodsPatients treated at a single center between October 2020 and April 2024 were included. The key innovation involves preoperative Doppler ultrasound mapping of perforating vessels combined with a "free-style" design principle, liberating the flap from constrained rotation and reducing the risk of dog-ear deformities associated with traditional hatchet methods. This approach enables an increased rotational arc. Outcomes were evaluated at follow-up using the Visual Analog Scale (VAS), Observer Scar Assessment Scale (OSAS), and Patient Scar Assessment Scale (PSAS).

resultsThis retrospective analysis included 65 patients (32 free-style, 33 traditional). All free-style flaps survived, whereas partial necrosis occurred in three traditional flaps. The free-style group showed improved aesthetic outcomes, including higher VAS scores, lower OSAS scores, shorter mean scar length, and lower PSAS scores, indicating greater patient satisfaction with scar appearance.

conclusionThe free-style perforator-based hatchet flap, facilitated by preoperative perforator mapping, was associated with better aesthetic outcomes and higher patient satisfaction compared to the traditional technique in this retrospective cohort.
