Comparison of fresh and frozen-thawed embryo transfer cycles in patients with low oocyte retrieval.
Article in Pakistan journal of medical sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Objective: To explore the choice of embryo transfer schemes for patients with low oocyte retrieval (≤ 3 oocytes). Methods: A retrospective analysis was conducted on patients with oocyte yields ≤ 3 undergoing in vitro fertilization and embryo transfer (IVF-ET) and frozen embryo transfer (FET) at the Maternity & Child Care Center of Qinhuangdao Reproductive Medicine Department from January 2018 to December 2022. The data included 202 fresh cycles, with 104 cycles in Group-A and 98 cycles in Group-B. Additionally, 87 cycles involved the transfer of frozen embryos from fresh cycles that could not be transplanted for various reasons, with 31 cycles in Group-C and 56 cycles in Group-D. General patient information, embryo transfer details, and clinical pregnancy outcomes in both fresh and frozen cycles were statistically analyzed. Results: No significant differences were observed between Groups A and C in age, anti-Müllerian hormone (AMH), basal follicle-stimulating hormone (bFSH), body mass index (BMI), duration of infertility, the proportion of patients with diminished ovarian reserve (DOR), oocyte retrieval count, usable embryo count, or the number of transplanted embryos (all p> 0.05). Advanced age was a risk factor for a decreased pregnancy rate, and FET significantly increased the pregnancy rate (p< 0.05, respectively). Conclusion: For patients under 35 years old with low oocyte retrieval, it is recommended to freeze all embryos when available and then proceed with FET. For patients aged 35 and above, without reducing the pregnancy rate, fresh embryo transfer is recommended to minimize treatment cycle frequency and economic expenses.
