One follicle, one egg, one embryo: a case-report of successful pregnancy obtained from a single oocyte collected.

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
In this report, we present an unusual case of a couple who achieved a successful pregnancy by ICSI with a single oocyte collected. The cumulus-oocyte-complex (COC) was retrieved at 36.5 hours post trigger, and was found to be at metaphase II, when sperm injection was performed at around 39 hours post trigger. At 18 hours post injection, the single oocyte was fertilized, developed to four-cell embryo on day 2, and 8-cell grade on day 3, when it was relocated in the uterine cavity. The pregnancy yielded a positive β-hCG result. The scan performed at seven weeks, revealed the presence of one amniotic sac with a fetal heartbeat. The ongoing pregnancy has been eventless at 24 weeks of gestation.
