[Pregnancy and obstetric outcomes of fresh embryo transfer versus frozen-thawed embryo transfer in women below 35 years of age].

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
objectiveTo compare the obstetric and perinatal outcomes between fresh embryo transfer (ET) and frozen-thawed ET (the "freeze-all" strategy) and evaluate the benefits of the "freeze-all" embryo strategy for young patients.
methodsWe reviewed a total of 2091 ET cycles performed between January, 2011 and December, 2015 in women aged 20-35 years, including 1295 fresh ET cycles and 796 frozen-thawed ET cycles. The demographic characteristics, ovarian stimulation syndrome, clinical pregnancy rates, live birth rate and the obstetric outcomes (gestational age, preterm delivery rate and mean birth weight) were compared between the two groups.
resultsThe mean age of the patients receiving frozen-thawed ET cycles had a significantly younger age than those having fresh ET cycles (29.5 vs 30.2 years, P<0.05); the patients undergoing frozen-thawed ET cycles also had significantly higher estradiol level on the day of trigger (12 973 pmol/L vs 8673 pmol/L) and a greater oocyte number retrieved (12.7 vs 8.7). The incidence of severe ovarian hyperstimulation syndrome was significantly lower in patients with frozen ET than those with fresh ET (P<0.05). No significant differences were found in the pregnancy rate (59.5% vs 56.0%; P>0.05), live birth rate (50.3% vs 47.0%; P>0.05), mean birth weight or gestational age between the two groups.
conclusionsThe freeze-all policy produces similar pregnancy and obstetric outcomes with those of fresh ET. Our results support the hypothesis that the freeze-all strategy help to prevent OHSS with a good pregnancy rate.
