Determinants of maternal vitamin D concentrations in Slovenia : A prospective observational study.
Observational study in Wiener klinische Wochenschrift, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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 analyze the vitamin D status of pregnant women in Slovenia and the factors influencing it.
methodsThe study was performed in Maribor University Medical Centre (location 46°N). Maternal serum 25-hydroxy-vitamin D (25(OH)D) in 4 groups of 100 pregnant women in 4 different seasons of the year was measured at the time of delivery. Data on life style, eating habits, sunbathing and intake of vitamin D supplements during pregnancy were obtained using a questionnaire. Information on maternal outcome was acquired from medical records. Duration of sunlight and average temperature in the month preceding delivery were calculated from meteorological data.
resultsThe average maternal 25(OH)D concentration ranged from 28.5 ± 17.1 nmol/l in March to 54.8 ± 24.1 nmol/l in June (p < 0.001). Severe vitamin D deficiency, i.e. <25 nmol/l 25(OH)D was present in 23.6% of women overall. In multiple regression analysis supplements containing vitamin D (β = 0.225, p < 0.001) and duration of intentional exposure to sunlight (β = 0.192, p = 0.026) were associated with maternal 25(OH)D status. Significantly lower vitamin D levels were observed in women who had a cesarean section (t = 2.053, p = 0.041) and those with premature delivery (t = 2.296, p = 0.022). Vitamin D levels were not associated with the occurrence of gestational diabetes, gestational hypertension or infections during pregnancy.
conclusionA high prevalence of vitamin D deficiency was detected at the end of pregnancy, especially in the months following autumn and winter and in women who did not take supplements containing vitamin D.
