Earliest evidence of rice cultivation in Remote Oceania: Ritual use by the first islanders in the Marianas 3500 years ago.

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
Rice was a staple crop in the ancestral Austronesian regions of Taiwan and Island Southeast Asia, but it was unknown in any of the Pacific Islands at the time of European encounters, with the exception of the unique case of Guam and the Mariana Islands. Through multiple methodologies, including phytolith analysis, micro-computed tomography scanning, and thin-section petrography, this recent research confirms the presence of abundant rice husk and leaf phytoliths adhering to red-slipped pottery ("Marianas Red") at the Ritidian Site Complex in Guam, dated by radiocarbon to 3500 to 3100 years ago. This study addresses the long-standing question of whether the first Pacific Islanders transported rice with them from the Philippines across 2300 kilometers of open sea, representing the longest known ocean voyage of the time. During this early period, rice was restricted to special ritual events in the Marianas. The early voyage apparently was planned with provisions of rice at 3500 years ago.
