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 Jomon culture that spread across the Japanese archipelago began about 16000 years ago and lasted for over 10000 years. The population history of the Jomon people, prehistoric hunter-gatherers bearing the Jomon culture, is of great interest in understanding prehistoric East Eurasians. Traditionally, population size and its fluctuations, i.e. Jomon demography, have been estimated in the archaeological context, but over the past 20 years, statistical methods using genome sequence data have been sufficiently developed. To investigate their demography, we determined the complete whole-mitochondrial genome (mitogenome) sequences from 13 Jomon individuals and conducted population genetic analysis on 40 Jomon mitogenomes, including previously published data. By simulation, we showed that east-west frequency differences between two haplogroups typical of the Jomon people, N9b and M7a, could be caused by a genetic drift under conditions of a small initial effective population size, an extreme population split, and limited migration between the eastern and western populations, suggesting that the regionally unbalanced haplogroup distribution does not necessarily contradict the monophyletic origin scenario of the Jomon people implied by recent nuclear genome analyses. We found an effective population size (
