Embryonic Aneuploidy after Preimplantation Genetic Screening: Age- and Indication-Matched Comparative Study between Indian and Spanish Population.
Article in Journal of human reproductive sciences. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundRecent studies show that there are differences in female fertility in different ethnic groups with ovarian aging and IVF treatment outcomes. Advanced maternal age is a known risk factor for miscarriage, accounting largely due to genetically abnormal fetus. AIMS AND
objectivesThis study investigates if there are any differences in rates of embryo aneuploidy based on age and indications for preimplantation genetic screening (PGS) between Indian and Spanish women. MATERIALS AND
methodsThis multicenter study was carried out at fertility centers in India and Spain. Data from autologous IVF cycles of women <45 years age (Spanish: 39.4 ± 3.8 years; Indian: 35.3 ± 4.6 years) were included. A total of 37,962 embryos from 7009 IVF cycles from Spain and 1894 embryos from 308 IVF cycles from India, having similar clinical indications, underwent similar IVF treatment protocol. The embryos were analyzed by PGS using either a day-3 or day-5/6 embryo biopsy.
resultsBoth Indian and Spanish ethnic population showed a reduction in aneuploidy rate in day-5/6 biopsy compared with day-3 biopsy (Spanish: 53.3% vs. 81.1%,
conclusionThis study shows that the aneuploidy rates between Indian and Spanish women of the same age group undergoing IVF treatment do not differ. An in-depth analysis to compare the types of anomalies reported with PGS in both the population will be of much interest.
