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
Fluorescence immunostaining for the phosphorylated H2AX histone (gammaH2AX) in the grasshopper Eyprepocnemis plorans has shown abundance of gammaH2AX in the nuclei of round and elongating spermatids, suggesting that DNA double-strand breaks (DSBs) occur regularly during spermiogenesis. Immunofluorescence patterns for Ku70, a DNA-repair protein participating in the non-homologous end-joining (NHEJ) pathway, showed that this protein is present in round and elongating spermatids, implying that the NHEJ DNA-repair pathway operates during chromatin compaction in spermiogenesis. In addition, during the final stages of spermiogenesis, the Ku70 protein concentrates on the region forming the sperm tail. Since Ku70 was also abundant in spermatid tails, it is reasonable to assume that Ku70 might play a novel function in sperm-tail formation. The analysis of Ku70 immunofluorescence patterns in 13 other grasshopper species also showed the presence of this protein in the nucleus and tail of elongating spermatids, indicating that this is a general characteristic in grasshoppers.
