1 · What the graph read from 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.

2 · The registry

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 recent improvement in sequential media has refocused its attention on the role of human blastocysts in ART, not only because of its advantages but also because of the possible cancellation of embryo transfer when relying on blastocyst transfer only. Hence, the idea of sequential transfer on day 3 and day 5 was proposed. Objective: To compare the pregnancy outcomes of sequential embryo transfer on day 3 and day 5, versus cleavage transfer on day 3 and blastocyst transfer on day 5 in cases of recurrent implantation failure.

methodsThis was a prospective and randomized trial, in which 210 qualified patients with recurrent implantation failures undergoing IVF/ICSI were randomized into three groups, each group included 70 patients. Embryo transfer was performed in day 3 in the first group, day 5 (blastocyst transfer) in the second group and sequential embryo transfer in days 3 and 5 in the third group. We assessed pregnancy outcomes from all the three groups. Results: Clinical pregnancy and live birth rates were significantly higher in the sequential group than either group day-3 or day-5 of embryo transfer in cases with recurrent implantation failures.

conclusionsSequential embryo transfer in cases with recurrent implantation failures and adequate number of retrieved oocytes is associated with higher implantation and clinical pregnancy rates, and it is advocated for patients having an adequate number of good quality embryos.
