The effect of combined oral contraceptive pills on angiogenesis in endometriotic lesions.
Trial report in Hormones (Athens, Greece), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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
purposeNeoangiogenesis is necessary for adhesion and invasion of endometriotic lesions. We hypothesize that by blocking angiogenetic pathways we can suppress endometriosis. Oral contraceptive pills (OCs) are routinely used in endometriosis to suppress symptoms of the disease. In the current study, we attempt to evaluate the effects of OCs on various angiogenetic factors in women with endometriosis.
methodsSixty women with endometriosis were randomly divided into two groups. Group A consisted of 30 women who received OCs in a cyclical manner for 3 months before surgery and group B of 30 women who did not. Biopsy specimens of ovarian endometrioma were collected. We used qRT-PCR to study the mRNA expression levels of VEGF, TF, PAR-2, SP1, and FGF1.
resultsThe levels of mRNA of all angiogenic factors were found to be elevated in women who received OCs compared with women who did not. This difference was statistically significant for VEGF, TF, FGF1, SP1 (p < 0.001), and PAR-2 (p = 0.046).
conclusionOC administration does not inhibit neoangiogenesis in endometriotic lesions; on the contrary, angiogenetic pathways might be upregulated.
