Our clinical study included 25 patients undergoing surgery for primary hyperparathyroidism. The measurement of basal circulating intact PTH (pg\/ml) and the volume (mm\n                    <jats:sup>3<\/jats:sup>\n                    ) of the removed gland(s) were recorded. It was essential for the distribution of the sample values to be normal before Pearson's correlation and regression analysis were performed. The Kolmogorov-Smirnov test showed sufficient sample data agreement (p&gt;20%) with normal distribution after their transformation into natural logarithm (ln) and so statistical analysis was performed utilizing ln transformed data. The regression line between basal ln of iPTH levels (x) and ln of tumor volume (y) was highly significant (y=2.3828+1.0424 x, r=.72504, p&lt;.0001). In our opinion, the above is a correct statistical procedure with reliable results.\n                  <\/jats:p>","DOI":"10.1177\/172460089701200304","type":"journal-article","created":{"date-parts":[[2018,4,16]],"date-time":"2018-04-16T10:26:37Z","timestamp":1523874397000},"page":"106-111","source":"Crossref","is-referenced-by-count":13,"title":["A Controversial Problem: Is There a Relationship between Parathyroid Hormone Level and Parathyroid Size in Primary Hyperparathyroidism?"],"prefix":"10.1177","volume":"12","author":[{"given":"F.","family":"Locchi","sequence":"first","affiliation":[{"name":"Nuclear Medicine, University of Firenze, Firenze - Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Tommasi","sequence":"additional","affiliation":[{"name":"Nuclear Medicine, University of Firenze, Firenze - Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.L.","family":"Brandi","sequence":"additional","affiliation":[{"name":"Endocrinology, University of Firenze, Firenze - Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Tonelli","sequence":"additional","affiliation":[{"name":"Surgery Units of the Department of Clinical Physiopathology, University of Firenze, Firenze - Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"U.","family":"Meldolesi","sequence":"additional","affiliation":[{"name":"Nuclear Medicine, University of Firenze, Firenze - Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1997,7,1]]},"reference":[{"key":"bibr1-172460089701200304","first-page":"25","volume":"16","author":"Brennan M.F.","year":"1983","journal-title":"Adv Surg"},{"key":"bibr2-172460089701200304","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800820723"},{"key":"bibr3-172460089701200304","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-198511000-00001"},{"key":"bibr4-172460089701200304","doi-asserted-by":"publisher","DOI":"10.1007\/BF01665302"},{"key":"bibr5-172460089701200304","doi-asserted-by":"publisher","DOI":"10.1177\/014107688708000816"},{"key":"bibr6-172460089701200304","doi-asserted-by":"publisher","DOI":"10.1007\/BF01665308"},{"issue":"6","key":"bibr7-172460089701200304","first-page":"1107","volume":"98","author":"Rutledge R.","year":"1985","journal-title":"Surgery"},{"issue":"3","key":"bibr8-172460089701200304","first-page":"360","volume":"88","author":"Broul\u00edk P.D.","year":"1986","journal-title":"Exp Clin Endocrinol"},{"key":"bibr9-172460089701200304","doi-asserted-by":"publisher","DOI":"10.1111\/j.1445-2197.1988.tb01084.x"},{"issue":"2","key":"bibr10-172460089701200304","first-page":"148","volume":"105","author":"Nikkil\u00e4 M.T.","year":"1988","journal-title":"Surgery"},{"key":"bibr11-172460089701200304","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9610(92)90007-E"},{"key":"bibr12-172460089701200304","first-page":"19","volume":"74","author":"Robertson G.S.M.","year":"1992","journal-title":"Ann R Coll Surg Engl"},{"key":"bibr13-172460089701200304","first-page":"497","volume":"49","author":"Piraneo S.","year":"1994","journal-title":"Minerva Chir"},{"key":"bibr14-172460089701200304","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2265.1995.tb02668.x"},{"key":"bibr15-172460089701200304","doi-asserted-by":"publisher","DOI":"10.1007\/s002689900154"},{"key":"bibr16-172460089701200304","unstructured":"SnedecorG.W., CochramW.S.
