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
Porcine CFL2b gene play an important role in the muscle development and myofibrillar formation in pig. To explore whether CFL2b expression affects muscle fiber trait, the porcine CFL2b full-length cDNA was amplified using homology based cDNA cloning and SMART RACE. Then the full length cDNA of porcine CFL2b was inserted into pEGFP-N1 and transfected into C2C12 cells. The cells stably expressing CFL2b were selected by G418. We examined the expression of MyHC 2x, MyHC 2b and MyHC1/slow in C2C12 cells stably expressing CFL2b. The results showed that the level of MyHC 2x and MyHC 2b mRNA were dramatically increased compared with control cells, while the level of MyHC1/slow mRNA is not changed. To identify the transcription events of CFL2b, the porcine CFL2b mRNA was detected by Northern blotting, two transcripts, long transcript (3,012 bp) and short transcript (1,466 bp) were found in porcine skeletal muscles. The nucleotide sequence of CFL2b shares 88.1 and 74.9% homology with the CFL2b gene in human and mouse. The deduced amino acid sequence of CFL2b (166 amino acids) in pig shares 100, 99.1% identity with the CFL2b in human and mouse, respectively. Taken together, our research revealed that porcine CFL2b may be involved in the regulation muscle fiber trait by affecting the expression of MyHC.
