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

Long COVID is defined by the occurrence of signs, symptoms, and conditions that develop after COVID-19 and may affect several organs and systems. Arginine-vasopressin deficiency (AVP-D; central diabetes insipidus) is a very rare complication of COVID-19 and SARS-CoV-2 immunization. Case reports, original studies, and reviews on AVP-D and long COVID published until February 2024 were retrieved from PubMed. A 47-year-old man presented with polydipsia, polyuria, memory loss, and mental fog 8 weeks after an episode of mild COVID-19. His past personal and family medical history were unremarkable. Biochemical evaluation was relevant for low urine osmolality and a 24-hour urine volume of 10,350 mL. Basal anterior pituitary evaluation was normal. A water deprivation test was started and interrupted after 2 hours due to the development of hypernatremia, high serum osmolality, and low urine osmolality. Urine osmolality significantly increased after intranasal desmopressin 20 μg. Contrast-enhanced pituitary MRI was suggestive of infundibulo-neurohypophysitis. Further biochemical, genetic, and imaging tests excluded secondary AVP-D causes.The patient was subsequently started on oral desmopressin, showing prompt response. After a follow-up of 20 months, he remained well-controlled with isolated AVP-D. Although molecular and histologic confirmation of SARS-CoV-2 infundibulo-neurohypophysitis could not be investigated, a strong temporal relationship and the absence of an alternative diagnosis rendered plausible the inclusion of AVP-D in the myriad of long COVID manifestations. Further studies with patients recovered from COVID-19 are necessary for a better understanding of the epidemiology, pathophysiology, and clinical course of this very rare endocrine condition.
