Invertebrate species with nonpelagic larvae have elevated levels of nonsynonymous substitutions and reduced nucleotide diversities.
Article in Journal of molecular evolution, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Under a nearly neutral model in which most amino acid substitutions are slightly deleterious, variation in demography, population structure, and other ecological factors among closely related species can potentially modify the effective population size or the selective regime, leading to differences in the rate of nonsynonymous substitution. Ratios of nonsynonymous to synonymous substitutions (d(N)/d(S)) between species were analyzed in a sea star genus (Patiriella) and a molluscan genus (Littorina), each with diverse modes of reproduction, including multiple lineages with pelagic and nonpelagic larvae. In both genera, lineages with nonpelagic larvae had significantly higher d(N)/d(S) ratios than lineages with pelagic larvae. The hypothesis that the elevated d(N)/d(S) ratios in species with nonpelagic larvae was due to reduced effective population size was tested by comparing nucleotide diversities in three genera of gastropod mollusks (Littorina, Crepidula, and Hydrobia), each with several modes of reproduction. Overall, there was a significant (p < 0.05) reduction in nucleotide diversity in species with nonpelagic larvae compared to species with pelagic larvae.
