Sunlight is an important determinant of vitamin D serum concentrations in cystic fibrosis.
Article in European journal of clinical nutrition, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 3 of them syntheses that pooled 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.
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/
objectivesThe increase of bone disease in adult cystic fibrosis (CF) patients is partly attributed to inadequate serum concentrations of 25-OH cholecalciferol (25 (OH) D) blamed on fat malabsorption. Based on physiological, clinical and biochemical observations this pathogenesis is debatable. The objective was to ascertain the relative importance of different 25 (OH) D sources. SUBJECTS/
methodsOver 4 consecutive years, 474 annual 25 (OH) D serum concentrations from 141 CF patients of all ages were compared with values of healthy peers and weighed against annual ultraviolet B (UVB) exposure.
resultsRanked per month, 25 (OH) D concentrations depicted a curve strikingly parallel to the amount of UVB exposure in the preceding months. A significant difference exists between 25 (OH) D concentrations in the 'Months with high UVB exposure' (May-October) and the 'Months with low UVB exposure' (November-April) but not with healthy controls in the same period.
conclusions25 (OH) D concentrations clearly respond to the amount of sunshine in preceding months. They are not clearly influenced by daily oral supplements of 800 IU of cholecalciferol. Sun exposure should be encouraged, and the recommended dosage of oral supplements increased.
