Effects of calpain genotypes on meat tenderness and carcass traits of Angus bulls.
Article in Molecular biology reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Relationships of the calpain system with meat tenderness and carcass traits were examined for 94 purebred Angus bulls with genotypes of the calpain classified by RFLP (restriction fragment length polymorphism) and SSCP (Single strand conformation polymorphism) analysis. Designing of primers based on the calpain regulatory subunit (CAPNS) and u-calpian (CAPN1) genes. Bulls from 15 months of age were slaughtered, and carcass traits, including fat thickness (FAT); longissimus muscle area (LMA); percentage of kidney, pelvic, and heart fat (KPH); hot carcass weight (HCW); marbling score (MAR); and quality grade (QUL), were analyzed. Measurements regarding meat tenderness involved activities of calpastatin (CAC), u-calpain (UAC), m-calpain (MAC), Warner-Bratzler Shear Force (WBS) and myofibril fragmentation index (MFI). Statistical significances of the calpain genotypes accounted for variations in MAR and QUL at CAPNS locus, and both loci explained variations of UAC and MAC. Significant mean differences in genotypes of CAPNS locus were found for MAR (BB > AB > AA) and QUL (AB > BB > AA). UAC showed significant correlations with MAC, CAC, MFI, FAT, and MAR, and we found that MAC correlated with WBS, FAT, HCW, MAR, and QUL. Strong positive correlation detected between LMA and HCW, and MAR and QUL, and a negative correlation between MFI and MAR was estimated. From the result it may be possible to use the calpain genotypes classified by RFLP and SSCP analysis in marker assisted selection programs to estimate UAC and MAC precisely regardless meat tenderness and to improve MAR and QUL of beef cattle.
