Evolution of the defensin-like gene family in grass genomes.
Article in Journal of genetics, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Plant defensins are small, diverse, cysteine-rich peptides, belonging to a group of pathogenesis-related defense mechanism proteins, which can provide a barrier against a broad range of pathogens. In this study, 51 defensin-like (DEFL) genes in Gramineae, including brachypodium, rice, maize and sorghum were identified based on bioinformatics methods. Using the synteny analysis method, we found that 21 DEFL genes formed 30 pairs of duplicated blocks that have undergone large-scale duplication events, mostly occurring between species. In particular, some chromosomal regions are highly conserved in the four grasses. Using mean Ks values, we estimated the approximate time of divergence for each pair of duplicated regions and found that these regions generally diverged more than 40 million years ago (Mya). Selection pressure analysis showed that the DEFL gene family is subjected to purifying selection. However, sliding window analysis detected partial reg ions of duplicated genes under positive selection. The evolutionary patterns within DEFL gene families among grasses can be used to explore the subsequent functional divergence of duplicated genes and to further analyse the antimicrobial effects of defensins during plant development.
