Outcome of HARMONIC Shears for lower limb free flap reconstruction in trauma: A retrospective cohort study.
Article in JPRAS open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: The HARMONIC Shears is an ultrasonic surgical device enabling precise tissue dissection with simultaneous hemostasis. Its application in lower limb free flap reconstruction following trauma is underexplored. Methods: A retrospective cohort study compared nine patients undergoing lower limb free flap reconstruction with HARMONIC FOCUS™+ Shears to nine patients using conventional dissection (diathermy and LIGACLIP clips). Patients were matched by flap type and concomitant orthopedic procedures. Primary outcome was total operative time. Secondary outcomes included flap survival, postoperative complications, length of hospital stay, and a comprehensive cost analysis encompassing theater time, consumables, and inpatient stay. Results: HARMONIC Shears significantly reduced operative time in cases without concomitant orthopedic procedures (262.8 ± 46.3 vs 364.2 ± 53.9 min; Conclusions: HARMONIC Shears may enhance operative efficiency and reduce healthcare costs in lower limb free flap reconstruction without compromising clinical outcomes. However, findings should be interpreted cautiously given the small sample size and limited statistical power. Larger prospective studies are warranted to confirm these findings.
