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
Background/aim: Knowing adenoma volume in patients with primary hyperparathyroidism is useful for surgeons during parathyroidectomy. The primary aim of our study was to identify the most accurate method for calculating adenoma volume. Our secondary aim was to determine the relationship between adenoma volume and preoperative biochemical parameters (parathyroid hormone [PTH] and calcium levels). Material and methods: The medical histories of 75 patients who underwent surgery for a single parathyroid adenoma were prospectively collected. After excision, the adenomas were placed in water-filled syringes, and their actual volume was determined according to the amount of water displaced. The radiological volume of the adenomas was calculated using the ellipsoid body formula according to the ultrasonographic dimensions. The PTH and calcium levels of the patients were retrieved from the patients' hospital records. Results: The calculated radiological volumes correlated with the actual adenoma volumes, but there were significant differences between the two measurements. A new formula was developed based on actual volumes and radiological volumes. A positive correlation was found between the adenoma volumes and the preoperative PTH and calcium levels. Conclusion: Adenoma volume calculated using a mathematical formula based on ultrasound measurements does not accurately reflect the actual volume. Higher preoperative calcium and PTH levels are associated with larger adenoma size.
