Joint test of historical vs. contemporary biogeography supports abundant center hypothesis shaping spatial patterns of self-fertilization.

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
Plant reproductive assurance describes the ability of a plant to successfully reproduce in an environment that is potentially devoid of conspecifics and/or pollinators. Traditionally, studies have focused on contemporary ecology-pollinator or mate availability-driving spatial patterns in reproductive assurance; however, historical processes-post-glacial range expansion-may be an understudied alternative explanation because during range expansion, selection should favor individuals with traits promoting reproductive assurance (i.e., autonomous selfing or clonal reproduction) at the range edge. While historical tests would be rooted in phylogeographic analyses, the role of contemporary ecology can be tested indirectly using the abundant center hypothesis, where it is assumed population density decreases from the range center toward marginal habitat. We used Northern pink monkeyflower-
