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

purposeThe probability of ovarian failure after cytotoxic chemotherapy in patients with breast cancer has not been well established in Korea. This study aimed to assess the rate of ovarian failure in a large cohort of Korean premenopausal patients with breast cancer 12 months after chemotherapy.

methodsThis retrospective cohort study included premenopausal women (aged 20-44 years) with breast cancer who underwent chemotherapy after surgery. The rates of treatment-related amenorrhea (TRA) and chemotherapy-induced menopause (CIM) at 12 months after chemotherapy were analyzed.

resultsA total of 237 patients met the inclusion criteria. The rate of TRA was 61.6% and that of CIM was 13.1% at 12 months after chemotherapy. The rates of TRA and CIM were 28.0% and 4.0%, respectively, in women aged 25-34 years, and they gradually increased up to 75.9% (TRA) and 15.8% (CIM), respectively, in women aged 40-44 years. The frequency of CIM was significantly lower than that of TRA in both age groups. In multivariate analyses, only tamoxifen use was significantly associated with a decreased risk of CIM (

conclusionMarked discrepancy in the rates of CIM and TRA was observed in this study. Further, the age-specific frequency of CIM and TRA observed in this study is a reliable and practical estimate of the risks of CIM and TRA in the absence of gonadal protection.
