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

backgroundDeveloped countries use generic competition to contain pharmaceutical expenditure. China, as a developing and transitional country, has not yet deemed an increase in the use of generic products as important; otherwise, much effort has been made to decrease the drug prices. This paper aims to explore dynamically the price and use comparison of generic and originator drugs in China, and estimate the potential savings of patients from switching originator drugs to generics.

methodsA typical hospital in Chongqing, China, was selected to examine the price and use comparisons of 12 cardiovascular drugs from 2006 to 2011.

resultsThe market share of the 12 generic medicines studied in this paper was 34.37% for volume and 31.33% for value in the second half of 2011. The price ratio of generic to originator drugs was between 0.34 and 0.98, and the volume price index of originators to generics was 1.63. The potential savings of patients from switching originator drugs to generics is 65%.

conclusionThe market share of the generics was lowering and the weighted mean price kept increasing in face of the strict price control. Under the background of hospitals both prescribing and dispensing medicines, China's comprehensive healthcare policy makers should take measures from supply and demand sides to promote the consumption of generic medicines.
