A cross sectional study of the autonomic function at different recovery phases in SARS-CoV-2 patients without orthostatic symptoms.

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
Autonomic nervous system involvement in COVID-19 survivors has been reported. This study aimed to assess heart rate variability (HRV) and baroreflex sensitivity (BRS) in COVID-19 survivors without orthostatic symptoms at different times after infection. Participants were classified as post-acute (PA, < 120 days) or long-term (LT, ≥ 120 days) according to time since positive swab. Mean heart rate (HR), time- (SDNN, RMSSD, pNN50) and frequency-domain (LF power, HF power, LF/HF) were computed. BRS was assessed by the sequence (BRS_seq) and the transfer function (BRS_TF) methods. We studied 37 PA and 36 LT patients and 50 age- and sex-matched healthy controls (HC). Compared to HC, PA patients exhibited significantly lower values for SDNN, RMSSD, pNN50, log-transformed LF and HF power, BRS_TF and BRS_seq, and higher HR and LF/HF ratio. Similar trends were observed in LT patients, with the exception of HR and LF/HF, where differences were not significant. Significant differences between PA and LT were found in HR (77.2 ± 10.7 vs. 69.8 ± 10.7 bpm, p = 0.002), log-transformed HF power (3.1 ± 1.2 vs. 3.8 ± 1.2 log-ms
