Risk factors predicting the occurrence of metachronous ovarian metastasis of gastric cancer.
Article in Annals of translational medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundOvarian metastasis following radical gastrectomy, also known as metachronous ovarian metastasis (MOM), pose a significant threat to the long-term survival of female gastric cancer (GC) patients. However, a mechanism to identify and characterize operated patients at high risk of developing MOM remains unknown. This retrospective study aimed to identify risk factors for the occurrence of MOM based on the profiling of clinicopathological parameters and expression of sex hormone receptors (SHR) of operated GC patients with and without ovarian relapse.
methodsThe clinicopathological data of 1,055 female GC patients from two medical centers who underwent surgery between January 2011 and December 2015 were reviewed. A total of 378 patients with and without the occurrence of MOM met the eligibility criteria, including the availability of medical records, adequacy of lymph node dissection, completeness of clinicopathological data, sufficient follow-up time, and no administration of neoadjuvant chemotherapy were selected for further analysis. Expressions of estrogen receptor alpha (ERα), estrogen receptor beta (ERβ), and progesterone receptor (PR) were detected by immunohistochemical staining on the surgical specimens of patients, and retrospective statistical analyses identified independent risk factors for the occurrence of MOM. A risk prediction model in the format of a polygenic hazard score (PHS) for the occurrence of MOM was established by introducing and modifying the previously validated polygenic risk score (PRS)/PHS.
resultsA Cox regression-based multivariate analysis identified premenopausal with an HR of 3.15 (95% CI, 1.66-5.98), more advanced pathological T stage with an HR of 3.79 (95% CI, 2.14-6.69), more advanced pathological N stage with an HR of 1.85 (95% CI, 1.35-2.54), and negative expression of ERβ with an HR of 0.33 (95% CI, 0.15-0.7) as independent risk factors for the occurrence of MOM (P<0.01). Accordingly, a PHS for the occurrence of MOM was established, with 1-, 2-, and 3-year ovarian relapse rates for the high-risk group estimated at 17.8%, 33.7%, and 46.2%, respectively.
conclusionsPremenopausal status, depth of tumor invasion, number of positive lymph nodes, and negative expression of ERβ were independent factors for the occurrence of MOM. More frequent follow-up examinations are recommended to provide timely diagnosis and medical intervention.
