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 most widely accepted model for the colonization of Remote Oceania by Austronesian-speaking bearers of the Lapita complex ~ 3 ka (3000 years ago) links it to a broader Neolithic expansion from China, via Taiwan, ~ 4.5-6 ka. However, analyses of mitochondrial DNA haplogroup B4a1a1a, prevalent among Remote Oceanians today, have both supported and challenged this scenario. Here, we analyze 1364 B4a1a1 mitogenomes (234 novel) from 68 islands and compare age estimates with radiocarbon dates for colonization. We estimate the settlement of Remote Oceania ~ 3.2 [2.7; 3.75] ka, matching radiocarbon ages, and then extrapolate the age in Near Oceania. B4a1a1a arose around the northern coasts of New Guinea at least 6 ka, following Early Holocene dispersals from Asia. Technological advances (e.g., in sailing), fueled by interaction networks alongside the arrival of Late Holocene migrants from Taiwan or ISEA and putative environmental changes, likely triggered the expansion of Lapita colonists carrying B4a1a1a from New Guinea into Remote Oceania.
