Relationships of phototextural characteristics of ovine presumptive zygotes to their developmental potential in vitro†.
Article in Biology of reproduction, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 vitro embryo production (IVP) has widespread implications for animal husbandry and conservation programs. The overarching goal of achieving pregnancy with IVP systems calls for accurate methods of embryo viability screening. The present study set out to examine whether phototextural attributes of ovine presumptive zygotes were reliable markers of embryo developmental competence in vitro. Sheep oocytes were obtained post-mortem from nine cycling Polish Longwool ewes using the ovarian cutting and sieving method. Following in vitro maturation of oocytes and their fertilization with fresh ram semen, the development of embryos (n = 37) was monitored using time-lapse imaging. The embryos were retrospectively classified as non-arresting (attaining the blastocyst stage; n = 6) or arresting (non-dividing presumptive zygotes or embryos arresting before the 7th mitotic division; n = 31). Commercially available image analytical software ImageProPlus® was used to generate bitmaps of the regions of interest comprising zygotic cytoplasm. Subsequently, a proprietary computer program r-Algo 2.0 was used to determine if there existed clusters of pixels for which first-order phototextural characteristics of presumptive zygotes' (t0) cytoplasm (i.e., mean pixel intensity (MPI), heterogeneity (MPH), and concentration (MPC)) differed significantly between the two subsets of embryos. Within the algorithmically identified pixel intensity ranges, future non-arresting embryos at t0 exceeded their arresting counterparts in MPI (pixel range of 73-75; 74.06 ± 0.01 vs. 73.98 ± 0.008; P = 0.0007) and MPC (pixel range: 105-106; 1.25 ± 0.22% vs. 0.56 ± 0.07%; P = 0.0004) but had lower mean MPH (pixel range: 36-42; 1.81 ± 0.04 vs. 1.97 ± 0.02; P = 0.0005). Computerized segmentation of ovine zygotic microphotographs is a promising non-invasive method to predict their developmental potential in vitro.
