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

backgroundInsufficient supply of vitamin D during early development may negatively affect offspring growth.

methodsWe examined the association between umbilical cord (UC) serum 25-hydroxyvitamin D (25(OH)D) concentrations and infant size in a study of two Faroese birth cohorts of 1038 singleton infants. In the third trimester, the pregnant women completed questionnaires, and clinical examination included birthweight, head circumference, and infant length at age 14 days.

resultsFifty-three percent of the newborn population had UC 25(OH)D < 25 nmol/L as determined by LC-MS/MS. Using multiple linear regression models with adjustment for pre-pregnancy BMI, sex, parity, gestational age, or infant age at examination, season of birth, smoking, gestational diabetes, examiner, and cohort identity, we found no relationship between birthweight or head circumference and UC 25(OH)D. However, infants with vitamin D status <12 nmol/L had a 0.49 (95% confidence interval 0.05, 0.93) cm lower length than infants with vitamin D status >50 nmol/L in models further adjusted for birthweight.

conclusionOur data suggest that umbilical cord serum 25(OH)D concentrations are positively associated with infant length but not with birthweight and head circumference. Although the paediatric relevance of the observed association is unclear, the possible long-term consequences of late-pregnancy hypovitaminosis D deserve attention.
