Proliferative activity of oxyphilic (Hurthle) cells in reactive and neoplastic thyroid lersions.

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
The proliferative potential of oxyphilic (Hurthle) cells (HCs) present in neoplastic and non-neoplastic thyroid lesions is uncertain. To estimate the HCs ability to proliferate and to determine whether their proliferative activity correlates with the biologic behavior of different thyroid oxyphilic lesions, we selected 31 cases of chronic lymphocytic (Hashimoto's) thyroiditis and 28 oxyphilic (Hurthle cell) thyroid tumors, including 12 adenomas and 16 carcinomas. Seven histologically normal thyroid specimens from euthyroid patients served as control tissue. The proliferative activity of HCs was evaluated by means of a double immunostaining for Ki67 and a mitochondrial antigen (which specifically recognizes oxyphilic cells). Oxyphilic cells in thyroiditis had a low proliferative activity (PA: 0.55%), although higher than that of normal thyroid parenchyma (PA: 0.06%). Neoplastic HC lesions had a mean proliferative activity of 1.56% and 6.26% in adenomas and carcinomas, respectively. A statistically significant difference was observed between proliferative activity of non-neoplastic and neoplastic lesions (p<0.01), but not within the tumor group, between adenomas and carcinomas. In addition, HC carcinomas had a statistically significant positive correlation between proliferative activity and tumor size (p<0.01) and the presence of necrosis (p<0.001).
