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
backgroundThe supraclavicular artery perforator (SAP) flap represents an excellent option for head and neck reconstruction; however, anatomical variability of the supraclavicular artery (SCA) impedes surgical standardization. This study aimed to establish a P-D-T (Pectoral-Deltoid-Trapezius) anatomical classification system based on vascular trajectory, validate the “point-line antegrade dissection” (PLAD) technique, and evaluate the impact of classification types on shoulder function and flap tolerance to prior radiotherapy.
methodsWe retrospectively analyzed 78 patients (80 flaps) undergoing SAP flap reconstruction between June 2016 and June 2025. Follow-up was censored on December 31, 2025. The P-D-T classification was established through cadaveric dissection of 20 hemibodies. Corrected pharyngocutaneous fistula rate was calculated among 65 digestive tract reconstructions. Radiation analysis included 59 patients (irradiated: 16; non-irradiated: 43). Shoulder function was assessed using Quick-DASH in 48 patients with minimum 6-month follow-up.
resultsThe 80 flaps were classified as Type I (Pectoral, 16.25%), Type II (Deltoid, 72.5%), and Type III (Trapezius, 11.25%). Overall flap survival was 98.75% (79/80), with corrected fistula rate of 6.2% (4/65). No significant difference in complication rates was observed between irradiated and non-irradiated groups (12.5% vs. 9.3%, P = 0.658). Quick-DASH scores differed significantly among types (P = 0.019); Type II showed higher scores than Type I (16.2 ± 7.3 vs. 9.1 ± 2.8, P = 0.017), but this difference (7.1 points) remained below the MCID threshold of 12–15 points.
conclusionsThe P-D-T classification combined with the PLAD technique enables precise SAP flap harvest. Preliminary findings support the feasibility of SAP flap in irradiated necks, demonstrating a complication profile comparable to non-irradiated cases, though validation in larger cohorts is warranted. Type II flaps demonstrate statistically significant but clinically mild shoulder functional impact.
