Pregnancy outcomes following in vitro fertilization using fresh or frozen embryo transfer.
Article in JBRA assisted reproduction, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 1 of them a synthesis that pooled 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.
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
objectiveThe aim of this study was to investigate the pregnancy outcomes in women undergoing IVF using fresh and/or frozen embryo transfer.
methodsIn this retrospective patient record study, we reviewed 2,872 infertile women's files, who were candidates for IVF. The patients were classified into two groups, including those who underwent fresh embryo transfer (n=1628) and/or frozen embryo transfer (FET) (n=1244).
resultsFertility was achieved in 313 (19.23%) and 356 (28.62%) patients, who underwent fresh ET and FET, respectively. The rates of clinical pregnancy, ongoing pregnancy, and live births were significantly higher in the FET group than the fresh ET group. The incidence of multiple pregnancies, perinatal mortality, abortion in the first trimester, preterm delivery, and low birth weight were significantly higher among fresh ET group [38 (35.51%), 15 (14.50%), 72 (23.01%), 26 (8.30%), and 33 (10.54%), respectively] than in the FET group [25 (15.33%), 6 (6.87%), 63 (17.69%), 14 (3.93%), and 20 (5.61%); p<0.05]. In addition, the incidence of ectopic pregnancies, abortion in the second trimester, gestational diabetes, preeclampsia, and placenta previa were higher in the fresh ET group, but not significantly so (p>0.05).
conclusionsWomen who underwent IVF via FET showed more successful fertility and pregnancy outcomes compared to those who underwent IVF by fresh ET.
