Required number of blastocysts transferred, and oocytes retrieved to optimize live and cumulative live birth rates in the first complete cycle of IVF for autologous and donated oocytes.

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 investigate live birth rate (LBR) and cumulative live birth rate (CLBR) to achieve the first newborn per blastocyst transferred and oocyte retrieved in the first complete IVF cycle of autologous and donated oocytes and identify the possible success factors.
methodsThis was a retrospective cohort study of a private IVF center. There were 1867 cycles, 1241 of which were fresh transfers and 626, their subsequent thawing transfers.
resultsWe found significant variables by binary logistic regression. For LBR, female infertility and the day of blastocyst transferred were relevant; however, for CLBR, the numbers of blastocysts available for future transfers, oocyte age, and maternal age were more critical. Oocyte age is a negative factor that begins to affect CLBR gradually beyond 36 years; from that age, there are significant worse results in polycystic ovary syndrome and poor responder patients.
conclusionThe LBR and CLBR were optimized for oocyte recipients when eight oocytes were retrieved (63.6%; 87.9%); at most, fourteen oocytes should be assigned to avoid freezing surplus blastocysts. Thirteen autologous oocytes (69.2%; 92.3%) were ideal for optimization. CLBR optimized after three blastocysts in donor oocytes (81.8%) and four for autologous oocyte patients (80.9%). Our outcomes are valuable for doctors and infertile couples, and they give us information on what we can expect from a first complete IVF cycle.
