Comparative study on the pregnancy outcomes of in vitro fertilization-embryo transfer between patients with different ovarian responses (a STROBE-compliant article).
Article in Medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
There have been few studies on large-sample data of cleavage-stage embryo and blastocyst transfers. We compared the pregnancy outcomes of patients with different ovarian responses after the transfer of different numbers of embryos in different developmental stages.Patients were divided into 3 groups including low response group, medium response group, and high response group according to different ovarian responses. Patients in each group were further divided into 4 subgroups including group A: transfer of 1 D3 embryo, group B: transfer of 2 D3 embryos; group C: transfer of 1 D5 blastocyst; and group D: transfer of 2 D5 blastocysts.In low ovarian responders, the implantation rate, clinical pregnancy rate and live birth rate were significantly lower in the group A than in the groups B and C. In medium ovarian responders, the implantation rate was significantly higher, but the multiple pregnancy rate was significantly lower in the group C than in the group B. The multiple pregnancy rate was significantly higher in the group D than in the group C. In high ovarian responders, the implantation rate was significantly lower, but the multiple pregnancy rate was significantly higher in the group B than in group C.Based on the above results, the single blastocyst transfer is preferable for the patients with different ovarian responses.
