Surgery for secondary hyperparathyroidism: mastering the anatomy - a single-center retrospective cohort study.
Article in BMC nephrology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis study aimed to evaluate the anatomical localization and distribution of parathyroid glands following total parathyroidectomy (TPTx) and bilateral cervical thymectomy (BCTx) in chronic hemodialysis patients with medically refractory secondary hyperparathyroidism (SHPT).
methodsA retrospective study on 154 consecutive SHPT patients with a mean hemodialysis duration of 109.3 ± 63.3 months was conducted.The study focused on the distribution of parathyroid glands within defined anatomical zones identified during surgery. Preoperative imaging methods (ultrasound and technetium-99 m sestamibi scintigraphy) provided limited diagnostic value, successfully localizing glands in only 34.6% and 31% of cases, respectively. Intraoperative parathyroid hormone (iPTH) measurement was not performed in any patient undergoing TPTx and BCTx.
resultsPostoperative success was defined by the normalization of iPTH levels, with 76.6% of patients achieving normal iPTH levels on postoperative day one (mean: 12.2 ± 14.1 pg/mL). Persistent SHPT was identified in 36 patients, leading to five complementary parathyroidectomies. The study demonstrated that the anatomical zones defined for parathyroid gland localization are reliable, exhibiting higher accuracy compared to preoperative imaging.
conclusionsThe findings support the feasibility of achieving high success rates with TPTx for SHPT, even when preoperative diagnostic tools are limited or ineffective. Knowledge of parathyroid gland distribution within these anatomical zones can significantly assist endocrine surgeons, particularly those who approach this condition with hesitation.
