1 · What the graph read from 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.

2 · The registry

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

purposeChronic kidney disease (CKD) is a common complication of patients affected by chronic hypoparathyroidism managed with conventional therapies. However, no data are currently available regarding the endocrine and metabolic determinants of renal function in these patients.

methodsThis was a multicenter observational study performed in three health-care centres. Patients with hypoparathyroidism were consecutively enrolled during follow-up visits in 2022-2023. These exclusion criteria were adopted: patients managed with dialysis, proteinuria (>200 mg/24 h), use of antihypertensive drugs including thiazides, ACE-inhibitors, angiotensin-II-receptor antagonists, alpha-beta blocking-agents, aldosterone-antagonists, and insulin-treated diabetes.

resultsA total of 46 patients were enrolled. Median age was 53 years, 34 (74%) were female and the median disease duration was 11 years. In all patients, the calcium-phosphate product was within the normal range. The 23.7% of patients was obese (BMI ≥ 30) and CKD (defined with an eGFR < 60 mL/min1.73m

conclusionsFor the first-time, obesity was demonstrated to be independently associated with CKD in patients with hypoparathyroidism, and a blunted eGFR-related response of FGF23 was shown in patients with CKD potentially worsening the renal function in the context of hypoparathyroidism.
