PATIENTS AND METHODS Twenty-three cases of ampulla of Vater adenocarcinoma were collected from archival material. For each sample, maspin, M3...
with error bars of 2 SD, the results may be seen in perspective (fig. 1, lower panel). The investigators described repeat testing for differences between the groups by Student's unpaired t test or by Mann— Whitney U test, and stated that they then confirmed the differences by analysis of variance or by Kruskal-Wallis. However, it is invalid to test repeatedly by Student's or by Mann-Whitney unl...

OBJECTIVE To compare dental and skeletal anchorages in mandibular canine retraction by means of a stress distribution analysis. METHODS A photoelastic model was produced from second molar to canine, without the first premolar, and mandibular canine retraction was simulated by a rubber band tied to two types of anchorage: dental anchorage, in the first molar attached to adjacent teeth, and ske...
