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

objectiveThis study aimed to investigate the effect of incorporating tumor laterality into the International Federation of Gynecology and Obstetrics (FIGO) staging system for advanced ovarian cancer.

methodsThe clinical data of 131 patients with advanced ovarian cancer treated between 2008 and 2018 were retrospectively reviewed. To investigate the prognostic significance of tumor laterality, we divided the patients into unilateral and bilateral groups. The prognostic significance of tumor laterality (bilateral vs. unilateral) was evaluated using univariate and multivariate analyses. The effect of incorporating tumor laterality into the FIGO staging system to predict survival outcomes was evaluated using the Kaplan-Meier method.

resultsBoth overall survival (OS) and progression-free survival (PFS) were longer in the unilateral group than in the bilateral group. Multivariate analysis demonstrated that tumor laterality was an independent predictor of OS (hazard ratio, 1.75; confidence interval, 1.05-2.92; P=0.032). In patients with stage III disease, the bilateral group had a shorter OS than the unilateral group, but it was comparable to the OS in stage IV patients (P=0.354). The incorporation of tumor laterality into the FIGO staging system improved the stratification of survival probabilities.

conclusionTumor laterality can be an independent prognostic factor in patients with advanced ovarian cancer. The incorporation of tumor laterality may improve the predictive performance of the FIGO staging system in patients with advanced ovarian cancer.
