Laser Microtomography for IVF Oocyte of Human.

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
For in vitro fertilization technology, the quality of oocytes has a direct impact on the egg fertilization and developmental competence of early embryo. The morphological criteria are used for the estimation of oocyte quality before its fertilization in vitro. To date, only one method is known to determine the maturity of oocyte. This is the routine observation with a light microscope. The aim of this article was to adapt the noninvasive quantitative laser scanning microtomography (QLSM) for the investigation of morphological features of a human oocyte in vitro. This approach was used to accumulate the Z-stack gallery of optical sections of IVF oocyte. The layer-by-layer acquisition allows the fine cytoplasmic structure imaging. Applying the QLSM Z-stack of optical sections, the cellular volume was calculated with quantitative 3D reconstruction of a human oocyte. The volume value and intracellular structure were used as novel criteria to assess the oocyte state after the stress evoked by cryopreservation procedure.
