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
The Smc5-Smc6 complex contains a heterodimeric core of two SMC proteins and non-Smc elements (Nse1-6), and plays an important role in DNA repair. We investigated the functional roles of Nse4 and Nse1 in Dictyostelium discoideum. Nse4 and Nse3 expressed as Flag-tagged fusion proteins were highly enriched in nuclei, while Nse1 was localized in whole cells. Using yeast two-hybrid assays, only the interaction between Nse3 and Nse1 was detected among the combinations. However, all of the interactions among these three proteins were recognized by co-immunoprecipitation assay using cell lysates prepared from the cells expressing green fluorescent protein (GFP)- or Flag-tagged fusion proteins. GFP-tagged Nse1, which localized in whole cells, was translocated to nuclei when co-expressed with Flag-tagged Nse3 or Nse4. RNAi-mediated Nse1 and Nse4 knockdown cells (Nse1 KD and Nse4 KD cells) were generated and found to be more sensitive to UV-induced cell death than control cells. Upon starvation, Nse1 and Nse4 KD cells had increases in the number of smaller fruiting bodies that formed on non-nutrient agar plates or aggregates that formed under submerged culture. We found a reduction in the mRNA level of pdsA, in vegetative and 8 h-starved Nse4 KD cells, and pdsA knockdown cells displayed effects similar to Nse4 KD cells. Our results suggest that Nse4 and Nse1 are involved in not only the cellular DNA damage response but also cellular development in D. discoideum.
