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

purposeThe prevalence of low birth weight (LBW) is increased in subjects born after assisted reproduction technology (ART), and defective imprinting has frequently been identified in patients with Beckwith-Wiedermann and Angelman syndromes conceived by ART. Thus, we examined methylation pattern in a girl born after ART who had Silver-Russell syndrome (SRS) which can be caused by maternal uniparental disomy for chromosome 7 and by hypomethylation of the differentially methylated region (DMR) of H19.

methodsWe examined methylation status of 31 cytosines at the CpG dinucleotides in the DMR of PEG1/MEST on 7q32.2 and 23 cytosines at the CpG dinucleotides in the DMR of H19 on 11p15, using leukocyte genomic DNA.

resultsEight of the 31 cytosines in the patient and four of the 31 cytosines in the father were hypermethylated in the PEG1/MEST-DMR. In the H19-DMR, no abnormal methylation pattern was identified in the patient.

conclusionThe results suggest that hypermethylation of paternally expressed genes including PEG1/MEST, which usually have growth-promoting effects, may be relevant to LBW in subjects conceived by ART.
