Pancreas attenuation in systemic sclerosis and control subjects. Graph showing the ratio of mean attenuation (CT number, Hounsfield units) for the pancreas (body + tail) in relation to the spleen in patients with and without fecal elastase values ≤ 210 μg/g and in control subjects, as a function of age. Group I (SSc with low levels of fecal elastase), circle/full black line; group II (age and sex-matched control subjects with SSc), triangle/dashed line; group III (age- and sex-matched control subjects without SSc): square/dotted line. The ratio shows an expected decrease with age. Significant difference was seen between group I and croup III (p = 0.024)
