Effects of Lymphovenous Anastomosis Surgery Using Ultrasonography in Lymphedema From a Pressure Perspective.
Article in Annals of rehabilitation medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo analyze the effects of lymphovenous anastomosis (LVA) surgery after 1 year using the elastic index (EI) and volume.
methodsThis study was a retrospective study of 41 patients, with lymphedema, who underwent LVA surgery between July 2018 and June 2020. Limb circumference, used to determine the volume of the limb with lymphedema, and EI, which reflects tissue stiffness and measured using ultrasonography were measured for each patient before and 1 year after LVA surgery. To examine the effect of LVA, differences in the preoperative and 1-year postoperative volumes and EIs were analyzed using the Wilcoxon signed-rank test.
resultsThe mean volume and EI of the dominant site in upper-extremity lymphedema were 2,309.4 cm3 and 1.4, respectively, preoperatively and 2,237.1 cm3 and 0.9, respectively, at 1 year postoperatively. The mean volume and EI difference of the dominant site 1 year after surgery was -16.6 cm3 (p=0.22) and -0.5 (p<0.001). The mean volume and EI of dominant site in lower-extremity lymphedema were 6,137.0 cm3 and 1.2, respectively, preoperatively, and 5,832.6 cm3 and 1.1, respectively, at 1 year postoperatively. The mean volume and EI difference of the dominant site 1 year postoperatively were -320.9 cm3 (p=0.04) and -0.2 (p=0.09), respectively.
conclusionLVA surgery is more effective in reducing pressure than in reducing volume, which may be helpful in preventing the progression of lymphedema.
