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

Objective: Aging affects both immune and autonomic regulation, yet their interaction remains poorly characterized. This study investigated how aging B-cell subpopulations, defined by CD21/CD11c expression, are associated with autonomic nervous system (ANS) dynamics, as measured by heart rate variability (HRV) during exercise in older adults. Materials and methods: In this cross-sectional study, 81 community-dwelling older adults (mean age 70.7 ± 5.8 years) underwent immune flow cytometry profiling of total B cells and four CD21/CD11c phenotypes. Continuous R-R interval (RRi) data were recorded at rest, during a standardized Two-Minute Step Test (TMST), and over a 5-min recovery period. A coupled-logistic RRi-vs-time model capturing each participant's cardiac autonomic signature (CAS) was obtained. Individual parameter estimates were regressed on standardized immune predictors using multivariate Bayesian models adjusted for age, sex and body composition. Results: Higher counts of CD21 Conclusion: CD21
