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

introductionhydroxyurea is the unique medication that has been proven to prevent complications in patients with sickle cell disease and is approved by the Food and Drug Administration. This medication requires a prescription to be dispensed, it must be available and at an affordable price. The purpose of this study was to determine the availability and market price of hydroxyurea in the Democratic Republic of the Congo and to make a comparison between these two aspects in a small city, such as Mbujimayi, and in a big city, such as Lubumbashi.

methodswe conducted a cross-sectional study in the context of a face-to-face survey involving 188 Congolese pharmacies from 1

resultshydroxyurea was available at 41/188 (22%) participating pharmacies, but more frequently at those of a big city than at those of a small city (34/96 versus 7/92). Most patients got a prescription (36/41; 88%). The average price of hydroxyurea was $15 (from $10 to $35 a blister packs of 25 capsules), which was higher than the purchasing power of the majority of sickle cell patients. Hydroxyurea is still an imported product from Europe, the United States or Asia.

conclusionshydroxyurea is one of the main treatments to slow down disease progression in sickle cell patients. Nevertheless, in the Democratic Republic of the Congo, its availability could be improved, in particular in small cities, and its price is still too high.
