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/

objectivesAnemia is a significant public health concern, especially among women and young children. An improved understanding of the complex etiology of anemia is crucial for developing appropriate prevention strategies. This paper examines the determinants of anemia in a large sample of Vietnamese women of reproductive age (WRA).

methodsWe included baseline data from 4986 WRA participating in a randomized controlled trial (PRECONCEPT). Hemoglobin (Hb) concentrations were measured with Hemocue. Plasma ferritin (Fe), retinol binding protein (RBP) and markers of inflammation were assessed using the ELISA technique. We used multivariate logistic regression to describe associations with anemia and structural equation modeling (SEM) to characterize direct and indirect pathways influencing Hb concentrations.

resultsPrevalence of anemia, iron deficiency (Fe <12 μg/l), insufficient iron stores (Fe<30 μg/l) and iron deficiency anemia was 19.7, 3.5, 14.4 and 1.9%, respectively. Ferritin concentration (0.29 per log-mg/dl), being an ethnic minority (-0.24 compared with Kinh), number of children (-0.17) and socioeconomic status (0.09) were directly associated with Hb concentration (P<0.05). Similarly, RBP was directly (0.27 per mg/dl) associated with Hb and also indirectly (0.09 mg/dl) with ferritin. Hookworm infection was indirectly associated with Hb (-0.11) through RBP and ferritin.

conclusionThese findings illustrate the complex etiology of anemia and provide a useful framework for designing, targeting and evaluating appropriate strategies for the prevention and control of anemia. Contrary to expectations, iron deficiency accounted for a very small proportion of anemia in Northern Vietnam.
