Outcome of gestational surrogacy according to IVF protocol.

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
purposeSurrogacy remains the only option for having a biologic child for a unique population of women with severe medical conditions. However, no study has looked at surrogacy outcome as a result of the type of ovarian stimulation of the intended mother [controlled ovarian stimulation (COH), modified natural cycle (MNC), and in vitro maturation (IVM)] for oocyte retrieval.
methodsThis is a retrospective study, including all intended mothers and gestational carriers in a tertiary, university affiliated, medical center, from 1998 to 2016.
resultsFifty-two women underwent 252 oocyte retrieval cycles. The pregnancy outcome of 212 embryo transfer cycles (64 gestational carriers) was reviewed according to the origin of the embryo. The number of retrieved oocytes was significantly higher following COH (n = 132) compared with IVM (n = 58) and MNC cycles (n = 62) (p = 0.013 and p < 0.0001, respectively). Pregnancy rates for embryos transferred according to each protocol were similar. All pregnancies that ended in live births when oocytes from IVM cycles were used derived from transfers of retrieved mature and mixed mature and immature oocytes. Pregnancies that involved embryos derived solely from immature oocytes that further matured in vitro and were transferred to gestational carriers were unsuccessful.
conclusionsMNC protocol is a good option to achieve pregnancy for intended mothers using gestational surrogacy who have contraindications to COH. The yield of IVM cycles in which immature oocytes are retrieved is inconclusive.
