Primary versus secondary cutaneous endometriosis: Literature review and case study.
Article in Heliyon, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
Cutaneous endometriosis, characterized by the presence of endometrium or endometrial-like tissue outside of the uterine cavity, is an uncommon and chronic disease. Depending on a patient's history, cutaneous endometriosis is classified as either primary cutaneous endometriosis (PCE) or secondary cutaneous endometriosis (SCE). We report a case of SCE presenting with the classic triad of previous caesarean section, subcutaneous nodules at the site of the scar, and pain associated with menstruation. Considering histopathology as the standard, we confirmed a diagnosis of cutaneous endometriosis by ultrasound and histopathology. Furthermore, we compared and analyzed the clinical characteristics of PCE and SCE, the study included 20 and 14 patients with cutaneous endometriosis diagnosed with PCE and SCE respectively. In the PCE group, the mean age of patients at the onset was 33.7 years, while it was 40.6 years in the SCE group. The mean disease-duration time of PCE was shorter than that of SCE (1.3 vs. 2.8 years, P > 0.05). The most common clinical presentation of PCE and SCE was a nodule (90% vs. 86%). The PCE was mainly bleeding with pain (45%), whereas the SCE of only pain and bleeding with pain accounted for the same proportion (45%). The most common sites of PCE and SCE were in the umbilical region (90% vs. 57%, P < 0.05). In our study, some statistically significant difference was found between different types of CE and it may contribute to improve clinicians' understanding of the disease, and perform early diagnosis and treatment.
