Identification of genetic variants in patients with primary and secondary amenorrhea.
Article in Saudi medical journal, 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
objectivesTo identify the cytogenetic and molecular pattern abnormalities and early diagnose the cause of primary and secondary amenorrhea.
methodsA total of 320 patients in the age group of 14-35 years with clinically confirmed amenorrhea were screened using conventional cytogenetic methods. Patients with a normal karyotype, hypoplastic uterus, and no hormonal imbalance were extensively investigated using molecular cytogenetic platforms such as chromosomal microarrays and clinical exome sequencing (CES).
resultsOf the 266 patients with primary amenorrhea and 54 with secondary amenorrhea, 66.9% and 88.9%, independently, had a normal karyotype. The 20 patients with a normal karyotype, hypoplastic uterus, and no hormonal imbalance were further evaluated for microdeletions of <5 megabases using chromosomal microarray. In 20 cases, 5 samples with no microdeletions were investigated for 150 target genes using CES. A pathogenic variant at chromosome X BMP15, c.661T>C, p.W221R, HET-XL-VUS was observed in one patient (reclassification).
conclusionCytogenetic evaluation of women with amenorrhea was performed in this study. One of the main etiological factors for primary amenorrhea is aberrant karyotypes. Identifying the underlying genetic cause may aid in devising effective treatment strategies. In addition, early diagnosis may enable treatment planning by the family before amenorrhea occurs.
