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

settingIn 2009, the World Health Organization (WHO) conducted a survey of the quality of four anti-tuberculosis drugs in the former Soviet Union countries. Kazakhstan had the highest proportion of substandard drugs.

objectiveTo assess the quality of anti-tuberculosis drugs used in Kazakhstan in 2014.

designFourteen anti-tuberculosis drugs from the Almaty Interdistrict TB Dispensary were randomly selected and screened for quality using Global Pharma Health Fund Minilab™ testing. First, the product and packaging were physically inspected to determine whether tablets/capsules were intact (i.e., whether they contained the full amount of the drug, and whether the packaging was genuine). Second, the tablets/capsules were dissolved in water to test whether they could be adequately absorbed by the body. Finally, semi-quantitive analyses were undertaken using thin-layer chromatography to verify the presence and concentration of the active pharmaceutical ingredient and to detect impurities.

resultsWe discovered no counterfeit medicines. However, 163 (19%) of the 854 anti-tuberculosis drugs sampled failed at least one of the three tests. These samples were found among 24/50 (48%) batches of 14 anti-tuberculosis drugs.

conclusionOur study identified a high proportion of poor-quality first- and second-line anti-tuberculosis drugs. Use of these medicines may lead to treatment failure and the development of drug resistance. Confirmatory testing should be performed to determine if they should be removed from the market.
