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

backgroundMany children worldwide have poor vitamin B12 status. The objective of this study was to estimate association between maternal and infant vitamin B12 status and long-term growth.

methodsWe randomly selected 500 Nepali mother-infant pairs and measured maternal intake and infant and maternal vitamin B12 status using plasma cobalamin, total plasma homocysteine, and methylmalonic acid concentrations. We revisited available children when they were 5 years old and measured growth. The associations between intake and maternal and infant markers of vitamin B12 and growth were estimated in multiple linear regression models adjusting for relevant confounders (n = 331).

resultsMaternal vitamin B12 intake and status and vitamin B12 status in infancy predicted linear growth at 5 years of age, but not during infancy. Each microgram increase in the vitamin B12 intake of the mother during infancy was associated with an increase in height of 0.4 (0.2, 0.6) height-for-age z-scores and 1.7 (0.7, 2.7) cm around the child's fifth birthday.

conclusionVitamin B12 status and intake in early life is an important determinant for linear growth at school age. Our findings should be verified in randomized, placebo controlled trials before translated into public health recommendations.
