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
introductionClinically, there has been increasing employment of the medial femoral condyle flap. Pigs have been employed as a model of the medial femoral condyle flap. However, related anatomical studies from the perspective of comparative medicine are rare. The objective of this study was to explore the vascular anatomy of the medial femoral condyle in pigs, explore the surgical procedure of the medial femoral condyle flap in pigs, and compare the medial femoral condyle flap in pigs and humans. MATERIALS AND
methods20 fresh cadaveric hindlimbs of hybrid pigs were used in this study. The origination, course, and branches of the vessels nourishing the medial femoral condyle were observed in 15 specimens. The variability in the anatomy of the vessels and the length and outer diameter of the vessels were evaluated. Surgical procedures for the medial femoral condyle flap were conducted on five specimens.
resultsThe nourishing artery of the medial femoral condyle in pigs was the second descending geniculate artery, which was observed in all 15 pigs and had a diameter and length of 2.013 ± 0.316 mm and 1.527 ± 0.212 cm, respectively. A skin incision of approximately 10 cm was used to harvest the medial femoral condyle flap of the pig in the supine position. After the adductor muscle was cut, the whole course of the second descending geniculate artery artery and its venae comitantes were exposed.
conclusionsThe vascular anatomy of the medial femoral condyle in pigs and that of humans exhibited great similarities. The medial femoral condyle flap in pigs was as easily harvested as that in humans. Pigs could serve as a suitable animal model for the medial femoral condyle flap.
