Heat stress attenuates the increase in arterial blood pressure during isometric handgrip exercise.

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
The purpose of this study was to examine arterial blood pressure responses during isometric handgrip (IHG) exercise performed at increasing levels of heat stress. Ten male subjects performed 1 min of IHG exercise at 60 % of maximal voluntary contraction under no heat stress (NHS), moderate heat stress [MHS, 0.6 °C increase in esophageal temperature (T (es))] and high heat stress (HHS, 1.4 °C increase in T (es)). For all conditions, IHG exercise significantly elevated mean arterial pressure (MAP) (NHS: 124 ± 6 vs. 90 ± 4 mmHg, MHS: 112 ± 6 vs. 89 ± 6 mmHg, HHS: 107 ± 7 vs. 91 ± 5 mmHg, P ≤ 0.05) and cardiac output (CO) (NHS: 9.0 ± 1.5 vs. 6.1 ± 0.6 L/min, MHS: 9.8 ± 1.8 vs. 7.6 ± 1.3 L/min, HHS: 10.0 ± 2.0 vs. 8.5 ± 1.9 L/min, P ≤ 0.05) relative to baseline, whereas no differences in total peripheral resistance (TPR) were observed (P > 0.05). However, the relative increases in MAP and CO were significantly reduced during MHS (MAP: 23 ± 6 mmHg, CO: 2.1 ± 0.9 L/min) and HHS (MAP: 16 ± 7 mmHg, CO: 1.5 ± 0.8 L/min) compared to NHS (34 ± 5 mmHg, CO: 2.9 ± 1.1 L/min, P ≤ 0.05). Furthermore, these elevations were significantly attenuated during HHS compared to MHS (P ≤ 0.05). Our findings show that heat stress attenuates the increase in arterial blood pressure during isometric handgrip exercise and this attenuation is cardiac output dependent, since TPR did not change during exercise for all heat stress conditions.
