Evaluation of efficiency of controlled pollination based parentage analysis in a Larix gmelinii var. principis-rupprechtii Mayr. seed orchard.
Article in PloS one, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Controlled pollination (CP) is an important tool for breeding programs to improve seed quality, as it rapidly generates desirable genotypes and maximizes genetic gains. However, few studies have evaluated the success rate of CP, especially in Larix gmelinii var. principis-rupprechtii Mayr. seed orchards. In this study, we estimated the rate of correct parentage in 257 CP progeny in an L. gmelinii var. principis-rupprechtii seed orchard from ten candidate parents using 13 microsatellites. The parentage exclusion probabilities of all combined loci in the single parent and parent pair tests were > 0.99, which was sufficient to distinguish the relatedness of the sampled individuals. Comparing the maximum likelihood-based parentage analysis results with breeding records revealed that the percentages of correctly identified maternal and paternal parents were 22.6% and 35.0% at 95% CL, respectively, suggestive of parent mislabeling and pollen contamination in the CP population. We conducted a pedigree reconstruction by identifying the expected parents and assigned maternity, paternity, and parent pairs to 176 (68.5%), 199 (77.4%), and 132 (51.4%) progeny, respectively. This study provides a reference for future selection of elite genotypes for commercial production. To increase the efficiency of CP, molecular markers should be used to correctly identify individuals in seed orchards before conducting CP.
