1 · What the graph read from 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.

2 · The registry

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

objectiveOur study aimed to identify mutations in the FMR1 gene in a group of Brazilian women diagnosed with primary ovarian insufficiency (POI).

methodsThis cross-sectional study included patients aged under 40 years with confirmed POI from a convenience sample of patients seen from June 2017 to December 2018 at a University Hospital in Curitiba, Brazil. Genomic DNA was extracted and analyzed using FragilEase(tm) PCR kits (PerkinElmer), a commercially available test that enables the quantification of CGG trinucleotide repeat expansions in the FMR1 gene.

resultsA total of 52 patients with an average age of 35.8±3.97 years were included. Fifty (96.1%) had normal alleles with 18 to 43 CGG repeats. The most frequent CGG-repeat sizes were 28 and 30. Two patients (3.8%) presented mutations in the FMR1 gene. The first had alleles with 19/97 CGG repeats, was categorized as a premutation carrier for FXS, and had a son with cognitive impairment. The second had alleles with 21/45 CGG repeats and was described as belonging to the gray zone.

conclusionsIn our study, 3.8% of the females with POI had mutations in the FMR1 gene. The most frequent allele sizes were 28 and 30 CGG repeats.
