Association Between COVID-19 and Orthostatic Intolerance in Children: A Retrospective Study.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
Introduction SARS-CoV-2 infection (COVID-19) and the COVID-19 vaccine have been linked to the development of persistent symptoms, including orthostatic intolerance (OI) and postural orthostatic tachycardia syndrome (POTS), in both children and adults. POTS is characterized by excessive tachycardia and other symptoms upon standing, significantly impacting quality of life. This study aims to evaluate the clinical and laboratory findings in pediatric patients with post-COVID-19 or post-COVID-19 vaccine OI and POTS. Methods This retrospective chart review included pediatric patients under 18 years of age with chronic dizziness or syncope following COVID-19 infection or vaccination. Autonomic studies, including the tilt table test, Valsalva maneuver, deep breathing test, and Quantitative Sudomotor Axon Reflex Test (QSART), were conducted to assess autonomic function. Data on clinical symptoms, autonomic testing results, and sweat production were collected and analyzed. Results In total, 16 patients (mean age 15 ± 3 years) were included in the study, with 14 patients developing symptoms post-COVID-19 infection and two post-vaccination. Ten patients (62.5%) met the criteria for POTS, with an average delta heart rate of 49 bpm on tilt table testing. Seven patients (43.75%) showed abnormal results on the Valsalva maneuver, and 50% (four patients) of those who underwent QSART demonstrated small fiber neuropathy. The mean standing norepinephrine level was 520 picograms per milliliter (pg/mL), with some patients showing markedly elevated levels. Conclusion This study highlights the growing incidence of POTS and other forms of OI in pediatric patients following COVID-19 infection and vaccination, supporting the link between COVID-19 and autonomic dysfunction in children. Our findings contribute to the growing body of literature on Long-COVID and emphasize the need for greater awareness, as well as further research into its long-term autonomic effects.
