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

Breast cancer remains the most common cancer among women worldwide. Many patients, especially in our region, are affected while young and during their child-bearing years. Chemotherapy, more commonly used in this age group, may result in premature ovarian failure and thus negatively impact their fertility. Several fertility-preservation methods are currently in use in this age group. Unfertilized ova cryopreservation and in vitro fertilization plus embryo cryopreservation are widely used in clinical practice. More recently, ovarian tissue cryopreservation is gaining in popularity. Several clinical trials and meta-analyses have shown that premenopausal women who received ovarian function suppression with gonadotropin-releasing hormone agonists while on chemotherapy were less likely to experience ovarian failure and had higher rates of menses resumption compared to those who did not. Some studies have also shown higher rates of successful pregnancies among treated patients. Given the conflicting results of the reported clinical trials and even the many published meta-analyses, this approach continues to be controversial and should only be used when other established fertility preservation methods cannot be utilized. The current review seeks to provide an updated summary on this controversial topic by reviewing all recently published clinical trials and meta-analyses.
