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 free anterolateral thigh flap has become a preferred option for skin defect reconstruction, particularly for heel ulcers. Due to the heel's weight-bearing role and potential bone destruction from ulcers, an anatomical-functional repair is essential for functionality restoration. This study reports long-term outcomes of a chimeric ALT fasciocutaneous flap combined with vastus lateralis muscle for calcaneal ulcer reconstruction, showing restored heel weight-bearing capacity. Methods: We retrospectively analyzed nine consecutive cases of heel ulcers from June 2020 to June 2022. All patients presented with exposed calcanei, five of whom had calcaneal infections. The nine cases underwent reconstruction using free anterolateral thigh (ALT) fasciocutaneous flaps combined with vastus lateralis muscle. The appearance of the flap and the functional recovery of the feet were assessed using the Freiburg ankle scoring system at the final follow-up visit. Results: The mean follow-up time was 12 months (range 6-18 months). The free flaps survival rate was 100 %. All patients had a successful return to ambulation. A linear scar remained in the donor site. The Freiburg score at the last follow-up was 73-95, with a mean of 88.5. According to the Freiburg scores, eight cases were good, and one case was moderate. Conclusion: After the long-term follow-up, the chimeric free anterolateral thigh flap and muscle flap may restore the weight-bearing function of the heel. It can make the patient back to work and daily activities, increasing the quality of life.
