Reconstructing the origin of the Lapita Cultural Complex: mtDNA analyses of East Sepik Province, PNG.
Article in Journal of human genetics, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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 colonization of Oceania occurred in two waves. By 32,000 BP, humans had reached New Guinea and settled all intervisible islands east to the Solomon Islands. Around 3,500 BP, a distinct intrusive group from Southeast Asia reached coastal New Guinea, integrated their components with indigenous resources, and gave rise to the Lapita Cultural Complex. Within 2,500 years, Lapita and its descendant cultures colonized the Pacific. To uncover the origin of the Lapita Cultural Complex, we analyzed the hypervariable region I of the mitochondrial deoxyribonucleic acid (mtDNA) in 219 individuals from eight East Sepik Province villages: two villages in each of four environmental zones. Same-zone villages spoke different languages: one Austronesian and three Papuan (Arapesh, Abelam, and Boiken). Our analysis examined whether language or geography better predicted gene flow. In general, language better predicted genetic affinities. Boiken villages across all four zones showed no significant genetic difference (F(ST) P value > 0.05). In contrast, the Austronesian village was significantly different to most other villages (P < 0.05). Only the mountains and coast showed zonal gene flow (P > 0.05). We interpret the data to reflect limited gene flow inland by Austronesians overshadowed by a regional displacement by inland Boiken speakers migrating seaward. These results are consistent with oral histories and ethnographic accounts.
