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

backgroundLow maternal choline intake and blood concentration may be risk factors for having a child with a neural tube defect (NTD); however, the data are inconsistent. This is an important question to resolve because choline, if taken periconceptionally, might add to the protective effect currently being achieved by folic acid.

objectiveWe examined the relation between NTDs, choline status, and genetic polymorphisms reported to influence de novo choline synthesis to investigate claims that taking choline periconceptionally could reduce NTD rates.

designTwo study groups of pregnant women were investigated: women who had a current NTD-affected pregnancy (AP; n = 71) and unaffected controls (n = 214) and women who had an NTD in another pregnancy but not in the current pregnancy [nonaffected pregnancy (NAP); n = 98] and unaffected controls (n = 386). Blood samples to measure betaine and total choline concentrations and single nucleotide polymorphisms related to choline metabolism were collected at their first prenatal visit.

resultsMean (±SD) plasma total choline concentrations in the AP (2.8 ± 1.0 mmol/L) and control (2.9 ± 0.9 mmol/L) groups did not differ significantly. Betaine concentrations were not significantly different between the 2 groups. Total choline and betaine in the NAP group did not differ from controls. Cases were significantly more likely to have the G allele of phosphatidylethanolamine-N-methyltransferase (PEMT; V175M, +5465 G>A) rs7946 (P = 0.02).

conclusionsOur results indicate that maternal betaine and choline concentrations are not strongly associated with NTD risk. The association between PEMT rs7946 and NTDs requires confirmation. The addition of choline to folic acid supplements may not further reduce NTD risk.
