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
objectiveDouble primary cervical cancer and ovarian cancer refer to the simultaneous or successive appearance of cervical cancer and ovarian cancer in the same patient. Due to the low incidence, there are few relevant reports. Therefore, this study is the first population-based analysis of the clinicopathological features as well as the prognostic status of double primary cervical cancer and ovarian cancer. We look forward to providing a reference for future clinical diagnosis and treatment.
methodsIn this study, 473 cases of double primary cervical cancer and ovarian cancer were collected from 1975 to 2019 through the SEER database. Double primary cancers were considered non-synchronous when they were diagnosed more than 6 months apart and were classified as Group A. Double primary cancers were considered synchronous when the interval between diagnosis of the two tumors was less than or equal to 6 months and was classified as group B.
resultsIn this study, the incidence of double primary cervical cancer and ovarian cancer accounted for 0.39% of primary cervical cancer and 0.24% of primary ovarian cancer in the same period. 80% of patients developed second cancer within 107 months of their first cancer being diagnosed. Compared with non-synchronous cancer, synchronous cancer is mainly characterized by simultaneous bilateral ovarian involvement and early clinical stage, but highly malignant, high lymph node metastasis rate, and poor prognosis.
conclusionMost patients developed second cancer within 107 months of their first cancer being diagnosed. Age at diagnosis, bilateral ovarian invasion, the interval between diagnoses, pathological type and stage of ovarian cancer, and grade of cervical cancer are important factors affecting survival, which still needs to be confirmed by more extensive studies in future.
