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

backgroundCurrently, oesophageal cancer is not a public health priority disease in Sub-Saharan Africa.

aimAnalysis of published scientific studies regarding oesophageal cancer in Sub-Saharan Africa was done to ascertain the incidence, prevalence and geographical distribution of the disease in the region.

methodsA pub med literature search was conducted for articles ranging from 1950 to 2009 database involving the following key words: oesophageal carcinoma, incidence, prevalence and sub-Saharan Africa.

results54 articles were retrieved, of which 16 were analyzed. Differences in the study methodologies used made the comparison amongst studies difficult. Overall, however, studies show that oesophageal cancer is on the increase in the region with its epicenter in the eastern and southern Africa. Incidence of the disease is higher in males than females and is prominent among 45-64 years age group in both sexes. Squamous cell carcinoma is a cell type more common than adenocarcinoma.

conclusionOesophageal cancer is on the increase in the Sub-Saharan African Region with uneven geographical distribution. Therefore, countries in the region are encouraged together with global health organizations to include oesophageal cancer amongst diseases of public health importance for effective prevention, early diagnosis and effective treatment.
