Desmopressin dose requirements in patients with permanent arginine vasopressin deficiency: a tertiary center experience.
Article in Pituitary, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeThe desmopressin daily dose requirement is highly variable among patients with arginine vasopressin (AVP) deficiency (i.e. central diabetes insipidus) and few studies to date have evaluated this topic, with often inconclusive results. The aim of our study was to identify clinical and biochemical predictors of such dose requirements in a cohort of patients with a confirmed diagnosis of permanent AVP deficiency who have good and stable control under substitutive treatment.
methodsWe retrospectively analyzed data of all patients with permanent AVP deficiency undergoing regular follow-up at our Division. Inclusion criteria were the presence of stable disease under therapy for at least 12 months and in good biochemical and clinical control. Patients with AVP deficiency who lacked intact thirst or had a disease duration of less than 12 months were excluded from the analysis.
resultsOut of the 132 patients initially screened, 96 patients (M/F 44/52; age 51 [37-63] years) met the inclusion criteria. Patients on nasal spray therapy (n = 8) had a significantly longer disease duration (p = 0.002) than patients treated with oral lyophilizate (n = 88). In the bivariate analysis, considering only patients treated with the sublingual formulation, the drug dose was correlated positively with estimated glomerular filtration rate (eGFR) and weight (r = 0.410, p < 0.001; r = 0.224, p = 0.036, respectively) and negatively with age (r = - 0.433, p < 0.001). In the multivariate regression analysis taking into account age, weight, and eGFR, only age emerged as a significant predictor of the required sublingual desmopressin dose (β = - 1.426, p = 0.044).
conclusionOur data suggest that patient age appears to be the primary factor associated with the daily sublingual desmopressin dose required to achieve adequate clinical and biochemical control in patients with permanent AVP deficiency.
