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

objectivesHigh prevalence of vitamin D deficiency mandates prescribing an appropriate form of vitamin D that allows attainment of sufficiency in a cost-effective manner. We aimed to compare vitamin D products in Indian market in terms of composition and cost in 2020 with 2013 to understand price dispersion over 7 years.

methodsConstituents, formulations, and prices of 'branded' and generic vitamin D products were sourced from various drug information compendia and online sources. Price per defined daily dose (DDD), percentage cost variation, and change in prices over 7 years (2020 vs. 2013) was determined.

resultsThere has been a disproportionate increase in the number of brands and cost variation of cholecalciferol and calcitriol in the last 7 years. The percentage cost variation increased almost 10 times for calcitriol and 4.4 times for alfacalcidiol tablets and cholecalciferol granules. An analysis of >1,100 products in 2020 showed that the predominant form was calcitriol which was combined with calcium in >90% of the products with huge cost variation (>3000%). Ergocalciferol and cholecalciferol were available in 22 and 15 different strengths respectively. Median price/unit of cholecalciferol (60,000IU) was lower for tablets/capsules compared to other formulations; but with >1000% cost variation.

conclusionA wide cost variation exists with the use of different vitamin D brands and preparations with conventional cholecalciferol tablets and capsules being a low-priced alternative. Quality control measures and strict enforcements of existing regulations are essential to ensure that competitive prices of branded generics are translated into availability and affordability for the population.
