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

The continent of Africa is the source of all anatomically modern humans that dispersed across the planet during the past 100,000 years. As such, African populations are characterized by high genetic diversity and low levels of linkage disequilibrium (LD) among loci, as compared to populations from other continents. African populations also possess a number of genetic adaptations that have evolved in response to the diverse climates, diets, geographic environments, and infectious agents that characterize the African continent. Recently, Tishkoff et al. (2009) performed a genome-wide analysis of substructure based on DNA from 2432 Africans from 121 geographically diverse populations. The authors analyzed patterns of variation at 1327 nuclear microsatellite and insertion/deletion markers and identified 14 ancestral population clusters that correlate well with self-described ethnicity and shared cultural or linguistic properties. The results suggest that African populations may have maintained a large and subdivided population structure throughout much of their evolutionary history. In this chapter, we synthesize recent work documenting evidence of African population structure and discuss the implications for inferences about evolutionary history in both African populations and anatomically modern humans as a whole.
