1 · What the graph read from it

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.

2 · The registry

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

Postoperative chemotherapy has been widely used in the treatment of early-staged ovarian cancer patients underwent unilateral resection, but the clinical decision mainly depends on the doctor's experience without a well-defined guideline. This study used propensity score matching to analyze the effect of postoperative chemotherapy for early-staged ovarian cancer patients underwent unilateral resection on prognosis. Patients of age 50 or younger than 50 with early-staged ovarian cancer were explored from the Surveillance, Epidemiology, and End Results program database during 2000-2018. Propensity score matching was used to randomize the dataset and reduce the selection biases. Univariate and multivariate cox proportional hazards models were utilized to estimate the necessity of chemotherapy. In univariate analysis of matched population, both the overall survival and cancer-specific survival analysis showed that chemotherapy had no effect on the prognosis of early-staged young ovarian cancer patients (Overall survival, P = 0.477; Cancer-specific survival, P = 0.950). In propensity-adjusted multivariate analysis, chemotherapy still had no effect on both the overall and cancer-specific survival probability after excluding the effect of all the confounding factors (HR = 0.863, CI = 0.587-1.269, P = 0.455; HR = 1.009, CI = 0.633-1.607, P = 0.970). Our study suggested that postoperative chemotherapy is not necessary for early-staged young ovarian cancer patients with unilateral resection, as indicated by both the overall survival and cancer-specific survival.
