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

objectiveIn young patients with early-stage epithelial ovarian carcinoma (EOC) who were received fertility-sparing surgery (FSS), the role of adjuvant chemotherapy is unclear. Here, we performed a multicenter study using inverse probability of treatment weighting (IPTW) to explore the effect of chemotherapy on patients' survival.

methodsBetween 1987 and 2015, a retrospective study was carried out, including 1183 patients with stage I EOC. Among them, a total of 101 women with stage I EOC who underwent FSS were investigated, including 64 and 37 patients with or without adjuvant chemotherapy, respectively. Oncologic outcomes were compared between the two arms using original and IPTW cohorts.

resultsDuring 62.6 months (median) of follow-up, recurrence was noted in 11 (17.2%) women in the chemotherapy arm and 6 (16.2%) patients in the observation arm. In the unweighted cohort, the 5-year overall and recurrence-free survival (OS/RFS) rates of chemotherapy and observation arms were 86.3/80.8 and 90.2/79.8%, respectively. There was no significant difference between the two groups {Log-rank: P = 0.649 (OS)/P = 0.894 (RFS)}. In the IPTW cohort after adjusting for various clinicopathologic covariates, we also failed to identify a difference in RFS/OS between the two groups {RFS (chemotherapy vs. observation), HR: 0.501 (95% CI 0.234-1.072), P = 0.075: OS (chemotherapy vs. observation), HR: 0.939 (95% CI 0.330-2.669), P = 0.905}.

conclusionsEven after adjusting clinicopathologic covariates, performing adjuvant chemotherapy may not improve the oncologic outcome in young patients who have undergone FSS.
