Secondary Hyperparathyroidism in Patients with Biliopancreatic Diversion After 10 Years of Follow-up, and Relationship with Vitamin D and Serum Calcium.

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
backgroundSecondary hyperparathyroidism (SHPT) is a matter of concern after biliopancreatic diversion (BPD). The aim of this study was to investigate the relationship between SHPT, 25(OH)D, and calcium after BPD.
designA retrospective analysis in obese patients after BPD performed between 1998 and 2016.
methodsPatients with at least 1 year of follow-up were included. SHPT was considered when PTH > 65 pg/mL in the absence of an elevated corrected calcium. 25(OH)D (ng/mL) status was defined as: deficiency < 20, insufficiency 20-29.9, and sufficiency ≥ 30.
resultsIn total, 321 patients were included (76.6% women), with mean age 43.0 (10.5) years. Median follow-up was 6.0 (IQR 3.0-9.0) years. Mean body mass index was 49.8 (7.0) kg/m
conclusionsOnce 25(OH)D is sufficient, the increase in PTH persists associated with a decrease in serum corrected calcium. It is important to ensure a sufficient calcium intake in these patients in order to avoid SHPT and osteomalacia in the future.
