Hereditary breast cancer and fertility preservation outcomes.
Article in Journal of assisted reproduction and genetics, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
purposeTo determine the frequency of hereditary breast cancer associated with different mutated genes and to evaluate fertility preservation (FP) outcomes among young women with hereditary breast cancer when compared to non-hereditary breast cancer. MATERIAL AND
methodsA retrospective cohort study of women with breast cancer who underwent fertility preservation treatment at our academic fertility center between 2005 and 2019. We included all women with breast cancer aged < 40 years who had a genetic testing and underwent fertility preservation before starting gonadotoxic therapy (n = 132). Our objective was to evaluate the total number of oocytes retrieved, mature oocytes MII, embryos (where appropriate), cryopreserved oocytes, and/or embryos.
resultsOf 132 women with breast cancer, 40 women were found to be genetically positive (31.4%), 31 women of 40 (77.5%) had a BRCA mutation, 3 (7.5%) had ATM, 2 (5%) had CHK2, and one (2.5%) for each of the following genes: PALP2, NF, MUTYH.c.536A, and TP53. There was no significant difference between the groups in the total number of eggs retrieved and the number of MII oocytes and cryopreserved oocytes. The numbers of fertilized oocytes and cryopreserved embryos in the hereditary (n = 40) and non-hereditary (n = 92) group were (5.15 ± 6.6 vs 2.90 ± 4.2, P = 0.054) and (3.35 ± 3.7 vs 1.9 ± 2.8, P = 0.046) respectively.
conclusionMore than three quarters of positive mutated genes in women with breast cancer are BRCA mutations. Compared to those with non-hereditary breast cancer, women with hereditary breast cancer attained higher number of cryopreserved embryos.
