Challenges and unmet needs in diagnosing polyuria-polydipsia syndrome: National survey by the Italian Society of Endocrinology.
Article in Journal of endocrinological investigation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
purposeSymptoms and baseline laboratory results often fail to identify the underlying cause of polyuria-polydipsia syndrome (PPS). A copeptin-based approach has recently been proposed for the differential diagnosis in adults. Given the rarity and complexity of PPS, national endocrinology societies should provide guidance to minimize diagnostic delays and ensure patients receive the most accurate evaluation.
methodsThe Hydro-Saline Club conducted a 22-question web-based survey targeting all endocrinologists registered with the Italian Society of Endocrinology in 2024. Data were collected from July 18 to September 22, 2024.
resultsA total of 120 endocrinologists from 75% of Italian regions completed the survey. 60% worked in university hospitals, while the remainder worked in peripheral hospitals and outpatient clinics. Copeptin testing was available in 58.3% of facilities. However, a basal copeptin evaluation was infrequently requested in PPS, mainly due to assay availability (p < 0.001) and low confidence in results interpretation, which correlated with clinical experience (p = 0.007). The WDT remained the most used stimulation test, with preference driven by personal experience (p = 0.020) rather than facility type. Familiarity with each diagnostic test increased with use, and test choice was apparently not influenced by concerns over potential side effects or accuracy. Rather, the main barrier identified was the perceived caregiving burden associated with the diagnostic process, leading many clinicians to prefer a stepwise diagnostic approach.
conclusionEndocrinological societies should promote awareness of novel, accurate diagnostic tools for PPS and support streamlined referral pathways to centers offering reliable, appropriate testing.
