Tracing back the origin of pumpkins (Cucurbita pepo ssp. pepo L.) in Mexico.
Article in Proceedings. Biological sciences, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Cucurbita pepo is an economically important crop, which consists of cultivated C. pepo ssp. pepo, and two wild taxa (C. pepo ssp. fraterna and C. pepo ssp. ovifera). We aimed at understanding the domestication and the diversity of C. pepo in Mexico. We used two chloroplast regions and nine nuclear microsatellite loci to assess the levels of genetic variation and structure for C. pepo ssp. pepo's landraces sampled in 13 locations in Mexico, five improved varieties, one C. pepo ssp. fraterna population and ornamental C. pepo ssp. ovifera. We tested four hypotheses regarding the origin of C. pepo ssp. pepo's ancestor through approximate Bayesian computation: C. pepo ssp. ovifera as the ancestor; C. pepo ssp. fraterna as the ancestor; an unknown extinct lineage as the ancestor; and C. pepo ssp. pepo as hybrid from C. pepo ssp. ovifera and C. pepo ssp. fraterna ancestors. Cucurbita pepo ssp. pepo showed high genetic variation and low genetic differentiation. Cucurbita pepo ssp. fraterna and C. pepo ssp. pepo shared two chloroplast haplotypes. The three subspecies were well differentiated for microsatellite loci. Cucurbita pepo ssp. fraterna was probably C. pepo ssp. pepo's wild ancestor, but subsequent hybridization between taxa complicate defining C. pepo ssp. pepo's ancestor.
