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

Anemia due to micronutrient deficiencies has received little attention in public health and modern-day clinical practice. Increasing numbers of persons, mainly in low- and middle-income nations, are faced with malnutrition and malabsorption syndromes, giving rise to various micronutrient deficiencies that can lead to anemias refractory to treatment with iron, folate or vitamin B12. Though relatively uncommon, such underlying nutrient deficiencies may be difficult to recognize as they can coexist with more common causes and there may be few or no specific clinical characteristics pinpointing a particular micronutrient. The main examples of these micronutrients contributing to a small but important burden of anemia are other B-group vitamins, pyridoxine and thiamine, ascorbic acid, the fat-soluble vitamins, A and E and other trace elements such as copper, zinc and selenium. The following review highlights the current state of knowledge and the relevance of these micronutrient deficiencies in the broader context of nutritional anemia.
