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
In the beetle genus Tribolium, satellite DNAs comprise a significant amount of pericentromeric heterochromatin and are characterized by rapid turnover resulting in species specific profiles. In the present work we characterize the major pericentromeric satellite DNA TCAST of the beetle T. castaneum and analyse its population dynamics. Using direct sequencing of genomic PCR products we show that the TCAST satellite exists in the form of two related subfamilies: Tcast1a and Tcast1b that make up 20 and 15% of the genome, respectively. Tcast1a and Tcast1b have consensus sequences of 377 and 362 bp respectively, share an average similarity of 79% and are characterized by a divergent, subfamily specific region of approximately 100 bp. The two subfamilies are prevalently organized in the interspersed form, although a portion exists in the form of homogenous tandem arrays composed of only Tcast1a or Tcast1b. The pattern of restriction enzyme digestion indicates that Tcast1a and Tcast1b are organized in composite higher order repeats. Comparison of sequence variability of Tcast1a and Tcast1b among ten strains reveals a difference in the frequency of particular mutations present at some positions. However, no difference in the organization and in the amount of subfamilies was detected among strains. The results show that direct genomic sequencing can be a useful method for the detection of population specific features of satellite DNA. In the case of TCAST satellite DNA, changes in the mutational profiles seem to represent the first step in the genesis of a population specific satellite profile.
