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

backgroundAdenomyosis affects the outcomes of spontaneous fertility and assisted reproductive technology. The single blastocyst embryo transfer (SBT) policy is an effective strategy known to minimize the risk of multiple pregnancy for non-adenomyosis women. However, little is known about its applicability to women with adenomyosis. The purpose of this study is to compare pregnancy outcomes between SBT, double-blastocyst embryo transfer (DBT), single-cleavage-stage embryo transfer (SET) and double-cleavage-stage embryo transfer (DET) in the frozen-thawed embryo transfer cycles among adenomyosis patients.

methodsThis retrospective study was conducted in all frozen-thawed autologous embryo transfer cycles. 393 frozen-thawed embryo transfer cycles performed in adenomyosis patients were enrolled. The major clinical outcomes were implantation rate (IR), clinical pregnancy rate (CPR), miscarriage rate (MR), multiple pregnancy rate (MPR) and live birth rate (LBR).

resultsThe SBT and DBT groups achieved higher IR (P < 0.001), CPR (P = 0.017), LBR (P = 0.040) and lower MR (P = 0.020) than the SET and DET groups. But the SBT and DBT groups achieved similar CPR and LBR. The SBT and SET groups achieved lower MPR (P < 0.001) than the DBT and DET groups. The average birth weight (BW) of SBT groups was higher than the DBT and DET groups (P = 0.016). When compared with SBT group, low-birth-weight infants were significantly higher with DBT and DET.

conclusionsWhen performing frozen-thawed embryo transfer cycles among adenomyosis patients, the SBT group has similar IR, CPR, MR, LBR but lower MPR compared to the DBT group. Therefore, SBT might be offered as standard practice.
