Visualization of meiotic spindle and subsequent embryonic development in in vitro and in vivo matured human oocytes.
Article in Journal of assisted reproduction and genetics, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
purposeThe aim of this study is to investigate the relationship between spindle location and embryonic development of in vivo and in vitro matured human oocytes.
methodsThe spindles of 134 in vivo matured, 105 in vitro matured oocytes were examined by Polscope at the time of ICSI.
resultsThe spindles were visualized in 83.6 and 77.1% of in vivo and in vitro matured oocytes respectively. The rate of fertilization of in vivo matured oocytes with spindles beneath or adjacent to the first polar body (angle of 0-5 degrees) was significantly higher (93.3%) than all other groups. The proportions of various spindle positions did not differ statistically in in vivo and in vitro matured oocytes.
conclusionsMeiotic spindle location with regard to the first polar body appears to influence fertilization rate.
