Effect of desmopressin on water and solute circadian rhythms in treatment-naïve children with monosymptomatic enuresis and nocturnal polyuria.
Article in Pediatric nephrology (Berlin, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundEnuresis has a complex pathophysiology involving nocturnal polyuria, reduced bladder capacity at nighttime, and impaired arousability. Desmopressin has long been used as a treatment. However, approximately 30% of children do not fully respond to it, suggesting the involvement of other factors. Solute handling and osmotic excretion have been studied in refractory patients. Nevertheless, data on the effect of desmopressin on these factors are sparse.
methodsWe conducted a post hoc analysis of the SLEEP study. We analyzed the circadian rhythm of solute and water excretion before and after desmopressin in 30 children with monosymptomatic enuresis and nocturnal diuresis > 100% of expected bladder capacity by means of a 24-h urine concentration profile (four daytime and four nighttime urine portions at equivalent time intervals).
resultsUnder desmopressin, nocturnal diuresis (rate) and Na/creatinine ratio were significantly lower compared to day values (p = 0.009, p = 0.021, respectively). Osmolality, Na/creatinine, and osmotic excretion showed a significant day vs. night variance only after desmopressin. Nighttime osmotic and sodium excretion were significantly lower (p = 0.004, p = 0.019, respectively) under treatment, indicating the impact of desmopressin on kidney sodium handling. During desmopressin treatment, nocturnal diuresis (rate) showed strong positive correlation with nighttime Na/creatinine (r = 0.436, p < 0.05) and very strongly with nighttime osmotic excretion (r = 0.875, p < 0.0001). However, no correlation was observed with osmolality under desmopressin treatment.
conclusionsThe anti-enuretic and antidiuretic effects of desmopressin therapy are not only related to urinary concentration and nocturnal diuresis but also to the amelioration of circadian rhythms of sodium and solute handling.
