Determinants of High Parathyroid Hormone Levels in Patients With Severe Obesity and Their Relationship With the Cardiometabolic Risk Factors, Before and After a Laparoscopic Sleeve Gastrectomy Intervention.
Article in Obesity surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundObesity is a risk factor for vitamin D deficiency and hyperparathyroidism. Hyperparathyroidism could exert a negative effect on glucose metabolism and vascular function. The aim of this study was to identify the determinants of hyperparathyroidism beyond vitamin D deficiency, whether hyperparathyroidism could have a negative impact on individual health and whether laparoscopic sleeve gastrectomy (LSG) negatively affects the levels of intact parathyroid hormone (iPTH) and 25(OH) vitamin D (25(OH)D).
methodsWe evaluated the levels of iPTH, 25(OH)D, and leptin, together with markers of insulin sensitivity and early cardiovascular disease, in a cohort of 160 patients with severe obesity before and after an LSG intervention.
resultsNinety-seven percent of subjects had vitamin D deficiency, and 72% of them had hyperparathyroidism. After correcting for possible confounders, we found a correlation between iPTH levels and carotid intima-media thickness, as well as with the HOMA index. After the LSG, 25(OH)D levels were significantly increased, while iPTH levels were significantly reduced. The reduction of iPTH was significantly correlated with the reduction of BMI, diastolic blood pressure, and leptin, which was the independent predictor of iPTH reduction.
conclusionsOur results suggest that vitamin D deficiency is not the sole determinant of hyperparathyroidism in severe obesity because visceral fat deposition and leptin could both play a role. Obesity-related hyperparathyroidism is associated with insulin resistance and atherosclerosis, although the results from previous studies were conflicting. Finally, LSG intervention does not negatively affect vitamin D status and improves hyperparathyroidism.
