Is tubal endometriosis an asymmetric disease? A 17-year retrospective study.
Article in Archives of gynecology and obstetrics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeTo investigate whether there are left-right asymmetries in tubal endometriosis and the factors affecting this predisposition.
methodsWomen who underwent salpingectomy for gynecological diseases and were diagnosed with tubal endometriosis between January 2002 and July 2019 were included in the study. The frequencies of left and right tubal endometriosis were compared with the expected 50% using a binominal test. The demographic characteristics and presence of ovarian endometrioid cysts, adenomyosis, and hydrosalpinx were also analyzed.
resultsDuring the study period of more than 17 years, 305 women were diagnosed with tubal endometriosis. The distribution of tubal endometriosis in the left or right fallopian tubes was analyzed. Tubal endometriosis was found in the left fallopian tube in 168 (55.08%) women, in the right fallopian tube in 93 (30.49%), and bilaterally in 44 (14.43%). Left unilateral tubal endometriosis was found most frequently (64.37%, 168/261), and its incidence was significantly higher than 50% (P < 0.001, binominal test). Furthermore, the frequency of left ovarian endometrioid cysts (58.82%) was higher than that of right ovarian endometrioid cysts (41.18%) (P < 0.001, binominal test).
conclusionOur study confirms that tubal endometriosis is a left-side asymmetric disease, and this predisposition is highly consistent with ovarian endometrioid cysts, which supports the transplantation theory of the origin of endometriosis.
