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
Objective: To investigate the effectiveness of free transverse gracilis myocutaneous flap for soft tissue defects of foot and ankle. Methods: Between January 2017 and December 2020, 16 cases (17 feet) of soft tissue defects of foot and ankle were repaired with free transverse gracilis myocutaneous flaps. There were 10 males and 6 females, with an average age of 38 years (range, 23-60 years). There were 9 cases of left foot, 6 cases of right foot, and 1 case of bilateral feet. The causes of soft tissue defect were traffic accident injury in 3 cases, heavy object smash injury in 4 cases, machine injury in 3 cases, infection in 4 cases, electrical burn in 1 case, and synovial sarcoma after operation in 1 case. The wounds located at the distal plantar in 2 cases (2 feet), the heel and ankle in 6 cases (6 feet), the dorsum of the foot in 7 cases (8 feet), and the first metatarsophalangeal joint to the medial malleolus in 1 case (1 foot). The size of wounds ranged from 6 cm×5 cm to 18 cm×7 cm. The size of flap ranged from 11 cm×6 cm to 21 cm×9 cm. The donor site was sutured directly. Results: After operation, 1 case (1 foot) of flap vascular crisis, 1 case (1 foot) of partial necrosis of the flap, and 1 case of partial dehiscence of the incision at donor site occurred, all of which healed after symptomatic treatment. The other flaps survived, and the incisions at donor and recipient sites healed by first intention. All patients were followed up 12-36 months (mean, 24 months). Except for 1 case (1 foot) of swollen flap, which underwent two-stage trimming, the other flaps had good shape and texture. All the flaps had a protective feeling. At last follow-up, Kofoed scores of foot and ankle function ranged from 73 to 98 (mean, 89.7); 13 cases were excellent, 2 cases were good, and 1 case was poor, with an excellent and good rate of 93.8%. Linear scar was formed at the donor site without adverse effect on lower limb function. Conclusion: The free transverse gracilis myocutaneous flap is an effective flap for repairing large soft tissue defects of foot and ankle due to its advantages of large excisable area, less variation of vascular anatomy, and concealment of donor site.
