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 indigenous Canary Islands population suffered a strong cultural and genetic impact when they were colonized by Europeans in the fifteenth century. The molecular analysis of the ABO blood group gene on aboriginal and seventeenth to eighteenth century remains confirms the demographic history of the islands depicted by previous archaeological, anthropological, and genetic studies. ABO allele frequencies clearly related Canarian aborigines with North African Berber populations, its most probable source of origin, and is far related to Iberian and to the current population of the archipelago. The historical sample shows a congruent intermediate position testifying already a strong European influence that would go in augment since then to present times, affecting all the islands with the important exception of La Gomera.
