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
Drosophila melanogaster protein kinase CK2 (DmCK2) is a Ser/Thr protein kinase composed of catalytic alpha and regulatory beta subunits associated as an alpha2beta2 heterotetramer. Using the two hybrid system, we have screened a Drosophila embryo cDNA library in order to identify proteins that interact with DmCK2alpha. One of these cDNAs encodes a novel previously undescribed zinc-finger protein, which we call ZFP47. ZFP47 interacts with DmCK2alpha but not with DmCK2beta, indicating that this interaction is specific for the catalytic subunit of CK2. In situ hybridization to polytene chromosomes indicates that the corresponding gene is located at the 72A interval of chromosome III. Sequence analysis indicates that ZFP47 contains a consensus site for phosphorylation by CK2, 4 C1H1-type zinc-fingers, and a bipartite nuclear localization signal. Consistent with the prediction of a site for phosphorylation by CK2, we demonstrate that ZFP47 is phosphorylated by CK2 purified from Drosophila embryos. These studies demonstrate that ZFP47 is a new physiological partner and substrate of CK2.
