DNA-flow cytometry of 207 pituitary adenomas: ploidy, proliferation, and prognosis.
Article in Journal of endocrinological investigation, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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 principal factors involved in pituitary adenoma formation are unknown. DNA-flow cytometry is a useful study providing an estimation of a tumor proliferative rate. In this study, DNA-flow cytometry was performed to evaluate its capability to both assess prognosis and predict recurrence. Two hundred and seven fresh pituitary adenoma specimens were assessed by flow cytometry. Pre-operative endocrine function, previous medical treatment, radiographic appearance, surgical findings and immunohistochemistry were recorded for each patient. Patient outcomes were assessed at a mean follow-up of 5.3 +/- 3.1 yr. Endocrinologically inactive pituitary adenomas were predominantly euploids (50.8%). The highest proliferation rates occurred in Nelson's syndrome and the lowest in Cushing's disease. A significant difference in proliferation was observed with prolactinomas and acromegaly when a medical treatment was performed before primary surgery. Massive histological invasiveness was directly associated with a significant increase in proliferation rate. Radiotherapy did not affect the recurrence rate (4.4%) statistically. In conclusion, DNA-flow cytometry was found to be useful for determining ploidy and obtaining an overview of cell cycle status. It was helpful in identifying patients requiring closer follow-up, such as those with invasive adenomas and Nelson's syndrome. No single parameter revealed by DNA-flow cytometry could predict tumor prognosis or recurrence in the follow-up of 7.5 +/- 1.3 yr.
