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

backgroundVitamin C or ascorbic acid is a hydro-soluble lactone (synthesized from glucose) essential to human body and available from diet. Despite its broad availability in fruits and vegetables, in many developing countries the incidence of clinical symptoms due to the vitamin deficiency is still very high. Also, pregnant women in the developing countries are frequently hospitalized for several preventable reasons such as anemia in pregnancy, mostly iron-deficient anemia (IDA) and the upper/lower respiratory tract infections (RTI). The aim of the study was to investigate, in a Ugandan rural pregnant women cohort, the preventive effects of vitamin C supplementation on hospital admission.

methods384 pregnant women met the inclusion criteria and were randomly assigned to receive either 400 mg of vitamin C daily (187) or not (197) in addition to their standard antenatal vitamins until delivery. The primary outcome measure of this study was to assess the prevention of hospitalization during pregnancy in the group of women supplemented with vitamin C compared to the controls. Fisher's exact test was employed in this assessment.

results42.2% women in the vitamin C group and 27.9% in the control group were not hospitalized during pregnancy; this difference was found statistically significant.

conclusionThe results of this study suggest including vitamin C in the guidelines of multivitamin prevention for pregnant women, especially in developing countries where seasonal availability of fruits and vegetables could result in adverse clinical outcomes.
