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

purposeWe investigated the acute effects of ecologically valid hot water immersion (HWI) and endurance exercise (END) interventions on indices of left (LV) and right ventricular (RV) function in middle-aged individuals with overweight or obesity.

methodsTwenty-five (15♀, 10♂) individuals were recruited. A single session of HWI (40 °C for 30 min with the water level at the sternum) and END (cycling 30 min at 60-70% of max heart rate [HR]) were carried out in randomised order, separated by at least 72 h. Core body temperature (Tc) and HR were monitored throughout each session. Blood pressure and ventricular parameters, including LV global longitudinal strain (LV GLS) and tricuspid annular plane systolic excursion (TAPSE), were assessed before and after each session.

resultsA significant increase in Tc was greater after HWI (Δ0.91 ± 0.32 °C) than END (Δ0.72 ± 0.29 °C; interaction: p = 0.004). Similarly, HR increased more after HWI than END (Δ33 ± 14 vs. Δ25 ± 12 bpm; p = 0.042) and HWI induced greater reductions in post-intervention SBP (Δ-5.7 ± 10.0 vs. Δ0.6 ± 6.6 mmHg; p = 0.019) and DBP (Δ-9.2 ± 9.2 vs. Δ-1.5 ± 5.1 mmHg; p = 0.001). There was a greater increase in LV GLS following HWI (Δ-2.5 ± 2.3%) compared to END (Δ-0.76 ± 2.09%; p = 0.008) and a significant increase in TAPSE after HWI (Δ3.95 ± 4.32 mm; p < 0.001).

conclusionWe observed greater increases in Tc, HR, and post-exercise LV and RV function following a HWI intervention compared to acute END. The physiological and practical importance of these differences should be explored further in long-term chronic programs in populations that could benefit from an alternative to the traditional END for cardiovascular benefits.
