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
B chromosomes are supernumerary genomic elements most likely derived from the standard (A) chromosomes, whose dispensability has freed their DNA sequences to evolve fast, thus making it difficult to uncover their ancestry. Here, we show the ancestry of a B chromosome in the grasshopper Eumigus monticola by means of the high-throughput analysis of the satellitome, i.e., the whole collection of satellite DNA (satDNA). The satellitome found in this species consists of 27 satDNA families, with monomer length between 5 and 325 nt and A + T content between 42.9 and 83.3 %. Two out of the 20 clustered satDNA families (EmoSat26-41 and EmoSat27-102) were observed only on the B chromosome. The A chromosome carrying the highest number of satDNA families was the megameric S8 (13 families), six of which were also present in the B chromosome, and three of these were exclusive of the S8 and B chromosomes. The absence in the B chromosome of the H3 histone gene cluster (located interstitially on S8) and three satDNA families (located distally on S8) allowed delimiting the possible origin of the B chromosome to the proximal third of the S8 autosome, through a breakpoint between EmoSat11-122 and the H3 cluster. Interestingly, bioinformatic analysis revealed the presence of seeds for the two B-specific satDNAs in the A chromosomes, suggesting their massive amplification in the B chromosome after its origin. Therefore, intraspecifically arisen B chromosomes can harbor DNA sequences apparently being B-specific.
