Visualization and examination of the meiotic spindle in human oocytes with polscope.
Article in Journal of assisted reproduction and genetics, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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 effect of detectability/location of meiotic spindle to fertilization of human MII oocytes and outcome of clinical IVF/ICSI-ET cycles was studied.
methodsThe location of spindle relative to polar body positioned to 6 o'clock was detected with polscope prior to ICSI in oocytes. Data of 83 IVF/ICSI-ET cycle, including pregnancy results, and a total of 1033 oocytes examined were analyzed retrospectively.
resultsPolar body position does not always accurately predict spindle position. Similar fertilization was observed in the polscope detected and in the control group. The main number of oocytes and spindle positive oocytes collected was higher in the pregnant than in the non-pregnant group. Higher fertilization was found in that group where 2/3-d of the oocytes had detected spindle. The main number of oocytes and spindle positive oocytes obtained decreased with increasing age of patients.
conclusionsThe presence of birefringent spindle predicts higher fertilization and development and greater probability of pregnancy.
