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

BACKGROUND/

objectivesHelicobacter pylori infection and iron and vitamin B(12) deficiencies are widespread in economically disadvantaged populations. There is emerging evidence that H. pylori infection has a negative effect on the absorption of these micronutrients. The aim of this study was to evaluate the effect of H. pylori infection on the efficacy of micronutrient (including iron and vitamin B(12))-fortified foods supplied for 1 year in marginally nourished children. SUBJECTS/

methodsIn all, 543 Indian children, aged 6-10 years, participated in a double-blind, randomized controlled intervention trial, receiving foods fortified with either high (100% Recommended Dietary Allowances (RDA)) or low (15% RDA) amounts of iron, vitamin B(12) and other micronutrients. The presence of H. pylori infection was diagnosed by the (13)C-labeled urea breath test at 11 months after the start of the intervention. Blood hemoglobin, serum ferritin (SF), total body iron and plasma vitamin B(12) were estimated at baseline and 12 months, and differences between these time points were assessed using an independent t-test.

resultsOverall, the prevalence of H. pylori infection in this group of children was 79%. Baseline hemoglobin, SF, body iron and vitamin B(12) concentrations were not associated with H. pylori infection. The response to the intervention (either high or low amounts of iron and vitamin B(12) fortification) in terms of change in iron markers and vitamin B(12) status did not differ between children with and without H. pylori infection.

conclusionsThis study shows that the presence of H. pylori infection did not affect the efficacy of long-term iron and vitamin B(12) fortification in these marginally nourished children.
