Microvessel density in human normal and neoplastic parathyroids.
Article in Endocrine pathology, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Objective. Information on angiogenesis in parathyroid pathology is scanty and in particular no data are available in parathyroid carcinomas. The aim of this study was to analyze angiogenesis as microvascular density (MVD) in parathyroid neoplastic progression from normal gland to adenoma and carcinoma. Methods. Sections from formalin-fixed, paraffin-embedded specimens of 33 normal parathyroids, 43 sporadic parathyroid adenomas, and 6 parathyroid carcinomas were cut for immunohistochemistry using anti-endothelial marker CD34. MVD was evaluated in each specimen as number microvessels per mm2. MVD data were compared with some anatomoclinical parameters as tumor size, serum calcium, and parathyroid hormone (PTH) level. Results. All normal parathyroid glands, all carcinomas, and 8 adenomas out of 43 (18%) showed MVD less than 100 microvessels/mm2 (median 70.8; 95%CI 66.9-88.5); in the majority of parathyroid adenomas (n = 35; 82%) the number of microvessels/mm2 was higher than 100 (median 188.3; 95%CI 174.9-210.1). In adenomas both preoperative serum intact PTH concentration and the diameters were significantly and inversely related to the microvessel density (r = 0.320, p < 0.05 and r = 0.334, p < 0.05, respectively). Conclusions. This study shows that in parathyroid adenomas MVD is heterogeneous and negatively related to the endocrine activity (secretory status and tumor size). Therefore, angiogenesis in parathyroid adenomas and carcinomas appears to be an early event, which does not follow a parallel increase in size.
