Genetic diversity in maize landraces from indigenous settlements of Northeastern Argentina.
Article in Genetica, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
In South America, native maize germplasm has been extensively studied particularly for the Andean region. However, relatively few genetic diversity studies include materials from the eastern region of the continent. Herein we present a genetic diversity characterization of four Popcorn maize landraces, maintained in indigenous settlements, from Northeastern Argentina (NEA). In addition, one Popcorn landrace from Northwestern Argentina (NWA) was incorporated for comparison. We characterized these landraces using ten microsatellite markers. For the whole data set, a total of 65 alleles were found, with an average of 7.22 alleles per locus. The average gene diversity was 0.370. Global fit to Hardy-Weinberg proportions was observed in all landraces. Global estimates of F (ST) revealed a significant differentiation among the populations. Individual Neighbor-joining clustering and Bayesian analyses allowed the recognition of most populations studied. Two main groups were distinguished by the Neighbor-joining clustering of populations. This grouping pattern would be consistent with a hypothesis of successive introductions of Popcorn in South America. The results presented will be useful to design strategies that maximize the utility of maize genetic resources.
