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
The highland region or Northwestern Argentina (NWA) is one of the southernmost areas of native maize cultivation and constitutes an expansion of the peruvian Andes sphere of influence. To examine the genetic diversity and racial affiliations of the landraces cultivated in this area, 18 microsatellite markers were used to characterize 147 individuals from 6 maize races representative of traditional materials. For the whole data set, a total of 184 alleles were found, with an average of 10.2 alleles per locus. The average gene diversity was 0.571. The observed patterns of genetic differentiation suggest that historical association is probably the main factor in shaping population structure for the landraces studied here. In agreement with morphological and cytogenetic data, Bayesian analysis of NWA landraces revealed the occurrence of three main gene pools. Assessment of racial affiliations using a combined dataset including previous data on American landraces showed a clear relationship between one of these gene pools and typical Andean races, whereas the remaining two gene pools exhibited a closer association to Caribbean accessions and native germplasm from the United States, respectively. These results highlight the importance of integrating regional genetic studies if a deeper understanding of maize diversification and dispersal is to be achieved.
