Quantitative investigation of the effect of surgically induced hypoparathyroidism on cataract development.

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
introductionAlthough cataract formation is known in hypoparathyroidism, lens clarity and its correlation with clinical parameters have not been investigated quantitatively before in patients with hypoparathyroidism. The aim of this study was to compare the crystalline lens clarity of patients with surgically induced hypoparathyroidism and healthy subjects. MATERIALS AND
methodsForty female patients with surgically induced hypoparathyroidism and 38 age-matched healthy female subjects were enrolled in this study. Scheimpflug corneal topography was performed to measure lens density (LD) and thickness (LT). Serum calcium, inorganic phosphorus, parathyroid hormone (PTH) levels, and disease duration were recorded.
resultsNo statistically significant difference was observed between the hypoparathyroidism and control groups in the Pentacam densitometry zones 1-2-3, LT, and average and maximum LD (p > 0.05 for all). Nine blue-dot-like, two cortical, and two posterior subcapsular cataracts were detected in the hypoparathyroidism group. The frequency of total and blue-dot-like cataracts was significantly higher in the hypoparathyroidism group than in the control group (p = 0.008 and p = 0.002, respectively). In the hypoparathyroidism group, a significant correlation was observed between the maximum LD and the hypoparathyroidism duration (ß = 0.420, p = 0.017), and the maximum LD and serum PTH level (ß = -0.332, p = 0.049).
conclusionThe clarity of the crystalline lens may decrease in surgically induced hypoparathyroidism patients depending on the disease duration and PTH levels. Additionally, this study detected an increased frequency of blue-dot-like cataract in the patient group, which may be due to the effect of hypoparathyroidism.
