Regular postexercise sauna bathing does not improve heart rate variability: A multi-arm randomized controlled trial.
Trial report in Physiological reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Regular exercise has been shown to increase heart rate variability (HRV) for different populations. Acute and short-term studies using heat therapy and sauna bathing have also shown HRV improvements. However, long-term adaptations in HRV to regular exercise and sauna bathing remain unexplored. In this 1:1:1 multi-arm trial, sedentary participants (n = 38) aged 49 ± 9 years with at least one CVD risk factor were randomly assigned to regular exercise and 15-min postexercise sauna (EXS), regular exercise only (EXE), or control (CON) group, for an 8-week intervention. Indices of HRV (RR interval, RMSSD, SDNN, resting heart rate [HR], HRMAX-HRMIN, high frequency power [HFP], and low frequency power [LFP]) were measured before (PRE) and after (POST) the trial. Compared to CON, EXE increased the time-domain measure of HR
