Heart Rate as a Predictor of 6-Month Pneumonia Risk in Patients With Dysphagia.

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
Objective: To determine whether resting heart rate (HR) or heart rate variability (HRV) derived from finger photoplethysmography (PPG) predicts 6-month pneumonia risk in patients with dysphagia. HRV reflects autonomic regulation of inflammation which may predispose to respiratory complications. Methods: A total of 301 patients who underwent a videofluoroscopic swallow study (VFSS) in 2020-2021 were enrolled. Prior to VFSS, resting HR was measured using the CorSense HRV finger sensor (ELITE HRV). Additional HRV metrics, including the standard deviation of normal-to-normal intervals (SDNN) and the root mean square of successive differences (RMSSD) were collected from a subset of 153 participants. Pneumonia incidence was assessed at 3 and 6 months through phone interviews and medical record review. Results: The mean age was 66.3 ± 12.5 years, and 38% were female. Twenty patients (7%) developed pneumonia, with 75% of cases occurring within 3 months. Patients who developed pneumonia had higher resting HR than those who did not (83.4 vs. 74.3 bpm, Conclusion: Elevated resting HR, though within the normal range, was associated with increased pneumonia risk in patients with dysphagia. This may reflect underlying inflammation or autonomic dysfunction. Because comorbidities, medications, and VFSS severity were not accounted for, these findings should be interpreted as preliminary. Resting HR may represent a simple, non-invasive tool for pneumonia risk stratification in this population, but larger studies are needed for validation. Level of Evidence: 2.
