Changing Trend in Vitamin D Status from 2008 to 2016: An Experience from a Tertiary Care Institute in North India.
Article in Indian journal of endocrinology and metabolism. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
backgroundSerum 25-hydroxyvitamin D (25(OH)D) assays have become readily available in India over the past decade. A large number of cross-sectional studies have been performed on the vitamin D status and the prevalence of vitamin D deficiency (VDD) in India. However, seasonal and long-term trends in serum 25(OH)D levels have been reported less frequently.
aimTo determine the seasonal and year-wise variation in vitamin D status at a tertiary care hospital in north India. MATERIALS AND
methodsUsing hospital records, the data on serum 25(OH) D assays performed in its endocrinology laboratory between 2008 and 2016 were obtained. For analysis of seasonal trends, the months of a year were divided into following seasons: March to June (summer season), July to October (rainy season), and November to February (winter season). VDD was defined as serum 25(OH)D concentration <20 ng/mL.
resultsA total of 26,339 assays of serum 25(OH)D were analyzed in the study. The year-wise assay numbers increased steadily from 2008 to peak in the year 2012, followed by a decline and a second smaller peak in the year 2016. The mean serum 25(OH)D concentration increased from 19.1 ± 16.4 ng/mL in 2008 to 21.7 ± 17.1 ng/mL in 2016 (
conclusionsThis study provides data on seasonal and year-wise trends in vitamin D status over a long period of time at a tertiary care hospital in north India. A long-term trend toward improving vitamin D status, especially in females, was noted in the study. The prevalence of VDD was found to decrease in the analyzed samples during the study period.
