A possible genetic basis for vulnerability in Euphydryas maturna (Lepidoptera: Nymphalidae).
Article in Genetica, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Nearly all of the known populations of Scarce Fritillary, Euphydryas maturna (Linnaeus, 1758), are declining in Western and Central Europe. In order to identify the possible reasons for its vulnerability we surveyed the population genetics of this butterfly species using multi-locus genotype data. Females of our target species lay lots of eggs in one or two batches only and pre-hibernation caterpillars live and feed gregariously in a nest. As a consequence, a random unfavourable event can eliminate most offspring of a particular female resulting in a strong genetic drift effect combined with inbreeding. Thus, our hypothesis regarding the genetic composition of Scarce Fritillary populations suggests that: (1) there will be random fluctuations in allele frequencies from generation to generation; (2) populations should exhibit small effective sizes and a relatively high level of heterozygote deficiency, and; (3) the majority of the individuals in a population will be composed of the offspring of just a few females. In order to test these hypotheses, fine-scale genetic structure was studied in two subpopulations of a Hungarian Scarce Fritillary population for 4 consecutive years (generations) using enzyme polymorphism data. The results supported all of our assumptions. We detected random fluctuation in the frequency of several alleles, small effective population size and the index of heterozygote deficiency (F
