Maternal serum vitamin D levels and preterm delivery among low-risk parturients in Lagos, Nigeria.
Article in International journal of gynaecology and obstetrics: the official organ of the International Federation of Gynaecology and Obstetrics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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.
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
objectiveTo determine the association between low maternal vitamin D levels and preterm delivery among parturients in Lagos, Nigeria.
methodsThe present study was an analytical cross-sectional study of women with preterm deliveries (defined as <37 weeks) and women with term deliveries (defined as ≥37 weeks) at the labor unit of Lagos University Teaching Hospital between December 1, 2015, and October 31, 2016. Relevant information was obtained via a proforma, and maternal venous samples were collected immediately after delivery. Serum 25-hydroxy vitamin D was determined by a vitamin D enzyme-linked immunoassay kit.
resultsThe study enrolled 103 women in each group. The overall prevalence of vitamin D deficiency was 14.1% (29/206). 24 (23.3%) women with preterm delivery had low serum vitamin D (<30 ng/mL) as compared with only 5 (4.9%) women with term delivery (P<0.001). Compared with normal serum vitamin D levels, low maternal vitamin D had an approximately nine-fold higher likelihood of preterm delivery (adjusted odds ratio 9.41, 95% confidence interval 2.42-36.54; P<0.001).
conclusionThe prevalence of serum vitamin D deficiency was higher among women with preterm delivery than among those with term delivery. The potential role of prenatal vitamin D supplementation in the prevention of preterm delivery should be further investigated.
