Hungry bone syndrome after parathyroidectomy in secondary and tertiary hyperparathyroidism: a retrospective cohort study.

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
Purpose: Hungry bone syndrome (HBS) is a common and critical postoperative complication in patients undergoing parathyroidectomy (PTX) for secondary hyperparathyroidism (SHPT) and tertiary hyperparathyroidism (THPT). We aimed to identify clinical predictors of HBS and assess its impact on bone mineral density (BMD) after PTX. Methods: We retrospectively analyzed data of patients with SHPT and THPT who underwent PTX at Asan Medical Center (2010-2022). Clinical characteristics, including biochemical markers and BMD, were investigated. HBS was defined as profound hypocalcemia of less than 8.4 mg/dL (2.1 mmol/L) or prolonged hypocalcemia for more than 4 days after PTX. Results: A total of 91 patients were included: 18 (19.8%) with SHPT and 73 (80.2%) with THPT. Subtotal PTX was performed in 80 patients (87.9%), while 11 patients (12.1%) underwent total PTX with autotransplantation (TPTX + AT). HBS occurred in 31 patients (34.1%), with a higher incidence in patients with SHPT (72.2%) and all patients who underwent TPTX + AT. Patients with HBS required more calcium supplementation and had higher ALP levels at all timepoints (P < 0.001). In the HBS group, BMD improved more significantly in the femur (P = 0.005) and showed a trend towards improvement in the spine (P = 0.059). Risk factors for HBS included younger age, SHPT, and elevated preoperative ALP and intact parathyroid hormone levels. Conclusion: HBS is characterized by severe hypocalcemia due to calcium reabsorption into bone after PTX. Identifying risk factors for HBS may promote early risk stratification and tailored perioperative management, including surgical approach, especially for high-risk patients.
