Effects of hyperthermia on the metabolic responses to repeated high-intensity exercise.
Trial report in European journal of applied physiology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 1 of them a synthesis that pooled 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.
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
In this study, we investigated the metabolic and performance responses to hyperthermia during high-intensity exercise. Seven males completed two 30-s cycle sprints (SpI and SpII) at an environmental temperature of 20.6 (0.3) degrees C [mean (SD)] with 4 min recovery between sprints. A hot or control treatment preceded the sprint exercise. For the hot trial, subjects were immersed up to the neck in hot water [43 degrees C for 16.0 (3.2) min] prior to entering an environmental chamber [44.2 (0.8) degrees C for 30.7 (7.1) min]. For the control trial, subjects were seated in an empty bath (15 min) and thereafter in a normal environment [20.2 (0.6) degrees C for 29.0 (1.9) min]. Subjects' core temperature prior to exercise was 38.1 (0.3) degrees C in the hot trial and 37.1 (0.3) degrees C in the control trial. Mean power output (MPO) was significantly higher in the hot condition for SpI [683 (130) W hot vs 646 (119) W control ( P<0.025)]. Peak power output (PPO) tended to be higher in the hot trial compared with the control trial for SpI [1057 (260) W hot vs 990 (245) W control ( P=0.03, NS)]. These differences in power output were a consequence of a faster pedal cadence in the hot trial ( P<0.025). There were no differences in sprint performance in SpII in the hot trial compared to the control trial; however, MPO was significantly reduced from SpI to SpII in the hot condition but not in the control condition ( P<0.025). Plasma ammonia was higher in the hot trial at 2 min post-SpI [169 (65) micromol l(-1 )hot vs 70 (26) micromol l(-1) control ( P<0.01)], immediately and at 2 min post-SpII [231 (76) micromol l(-1) hot vs 147 (72) micromol l(-1) control ( P<0.01)]. Blood lactate was higher in the hot trial compared with the control trial at 5 min post-SpII ( P<0.025). The results of this study suggest that an elevation in core body temperature by 1 degrees C can improve performance during an initial bout of high-intensity cycle exercise but has no further beneficial effect on subsequent power production following a 4-min recovery period.
