Selection of AVP-Shortage Patients as Candidates for Low-Dose Oral Desmopressin Administration.
Article in Research and reports in urology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveWe herein attempted to select male patients with an elevated nocturnal urinary frequency possibly due to a shortage of AVP. These patients may be good candidates for low-dose oral desmopressin administration. PATIENTS AND
methodsSerum and spot urine osmolality, electrolytes, serum creatinine, casual blood glucose, plasma brain natriuretic polypeptide (BNP), and plasma AVP were measured at the same time in 97 elderly male patients with urinary symptoms under free water drinking.
resultsA binary plot of plasma AVP and serum osmolality indicated a region at which patients had relatively lower AVP considering higher serum osmolality. It was tentatively named the desmopressin region. Twenty out of 97 (20.6%) patients were in the desmopressin region. Daily urine output did not exceed 3 L in any patient. Urine osmolality was slightly lower in patients in the desmopressin region. No significant differences were observed in urine volume, urinary frequency, or urination questionnaire scores between both groups.
conclusionAVP-shortage patients may be selected for treatment with oral desmopressin based on measurements of serum osmolality and plasma AVP.
