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

introductionThe aim of this study was to evaluate the oncologic outcome of women with stage I ovarian endometrioid carcinoma (EC) who underwent fertility-sparing surgery (FSS). MATERIALS AND NETHODS: Between 1986 and 2017, a total of 3227 patients with epithelial ovarian carcinoma were retrospectively evaluated based on a central pathological review and search of the medical records from multiple institutions. We identified 24 and 54 patients with stage I EC who underwent FSS and conventional radical surgery (CRS), respectively. Inverse probability of treatment weighting (IPTW)-adjusted Kaplan-Meier and Cox regression analyses were employed to compare OS between the two groups.

resultsWith follow-up of a total of 78 patients, 9 patients (11.5%) developed recurrence. In addition, 5 patients (6.4%) died of the disease. Recurrence was noted in 3 (10.7%) patients in the FSS group and 6 (11.1%) patients in the CRS group. Death was noted in 2 (8.3%) patients in the FSS group and 3 (5.6%) patients in the CRS group. In the original cohort, there was no significant difference in overall survival (OS) or recurrence-free survival (RFS) between the FSS and RS groups {Log-rank: OS (P = 0.630), RFS (P = 0.757)}. In the IPTW-adjusted cohort, the 5-year OS rates were 96.6 and 92.4% in patients with FSS and CRS, respectively (P = 0.319). Furthermore, the 5-year RFS rate was 88.6% for the FSS group and 88.1% for the CRS group (Log-rank: P = 0.556).

conclusionsYoung women with stage I EC undergoing FSS showed a relatively satisfactory prognosis, equal to those receiving CRC.
