HIRA is essential for the development of gibel carp.
Article in Fish physiology and biochemistry, 2014. 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
HIRA is one of the chaperones of histone H3.3. Mutation of Hira results in embryonic lethality in mice, suggesting a critical role in embryogenesis. However, Hira-mutated Drosophila may survive to adults, indicating that it is dispensable in Drosophila development. The role of Hira in fish development is unknown. In this study we first investigated the expression of Hira during embryogenesis of gibel carp (Carassius auratus gibelio) by whole-mount in situ hybridization. We found that Hira signal appeared ubiquitously in the early embryos. After gastrulation, it appeared mainly along the anterior-posterior axis, including the tail bud. In hatching period, the signal was detected in head, heart, and the endoderm region on the back of yolk. Then by microinjection with morpholino-HIRA at the beginning of development, we observed delayed gastrulation and abnormal somitogenesis in gibel carp embryos. The HIRA morphants exhibited short trunk, limited yolk extension, and twisted tail. Most of the mutants died during embryogenesis or shortly after hatching. The rest of the HIRA morphants could survive to larvae but with severe defects in organogenesis. These data suggest that HIRA may be essential for the development of gibel carp, and this function is conserved in vertebrates.
