Trial report in Obesity (Silver Spring, Md.), 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02663362 (Development and Validation of Multi-nuclear Magnetic Resonance Imaging and Spectroscopy for Whole Body Human Applications), which is not on this map.

1 · What the graph read from it

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.

Abstract

objectiveMuscle triglyceride can be assessed in vivo using computed tomography (CT) and 1H magnetic resonance spectroscopy (MRS), two techniques that are based on entirely different biophysical principles. Little is known, however, about the cross-correlation between these techniques and their test-retest reliability. RESEARCH METHODS AND PROCEDURES: We compared mean muscle attenuation (MA) in soleus and tibialis anterior (TA) muscles measured by CT with intra- and extramyocellular lipids (IMCL and EMCL, respectively) measured by MRS in 51 volunteers (26 to 72 years of age, BMI = 25.5 to 39.3 kg/m2). MA of midthighs was also measured in a subset (n = 19). Test-retest measurements were performed by CT (n = 6) and MRS (n = 10) in separate sets of volunteers.

resultsMA of soleus was significantly associated with IMCL (r = -0.64) and EMCL, which by multiple regression analysis was explained mostly by IMCL (p < 0.001) rather than EMCL (beta = -0.010, p = 0.94). Muscle triglyceride was lower in TA than in soleus, and MA of TA was significantly correlated with EMCL (r = -0.40) but not IMCL (r = -0.16). By CT, MA of midthighs was correlated with MA in soleus (r = 0.40, p = 0.07) and whole calf (r = 0.62, p < 0.05). Finally, both MA and IMCL were highly reliable in soleus (coefficient of variation = < 2% and 6.7%, respectively) and less reliable in TA (4% and 10%, respectively). DISCUSSION: These results support the use of both CT and MRS as reliable methods for assessing skeletal muscle lipid.
