Salivary Hsp72 does not track exercise stress and caffeine-stimulated plasma Hsp72 responses in humans.
Trial report in Cell stress & chaperones, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Heat shock protein 72 (Hsp72) has been detected within saliva, and its presence may contribute to oral defence. It is currently unknown how physiological stress affects salivary Hsp72 or if salivary Hsp72 concentrations reflect plasma Hsp72 concentrations. We studied the effect of exercise upon salivary Hsp72 expression, and using caffeine administration, investigated the role of sympathetic stimulation upon salivary Hsp72 expression. Six healthy males performed two treadmill running exercise bouts in hot conditions (30°C) separated by 1 week in a randomized cross-over design, one with caffeine supplementation (CAF) the other with placebo (PLA). Plasma and saliva samples were collected prior to, during and post-exercise and assayed for Hsp72 concentration by ELISA. Exercise significantly increased plasma Hsp72, but not salivary Hsp72 concentration. Mean salivary Hsp72 concentration (5.1 ± 0.8 ng/ml) was significantly greater than plasma Hsp72 concentration (1.8 ± 0.1 ng/ml), and concentrations of salivary and plasma Hsp72 were unrelated. Caffeine supplementation and exercise increased the concentration of catecholamines, salivary α-amylase and total protein, whilst the salivary Hsp72:α-amylase ratio was lower in CAF. Salivary Hsp72 was not altered by exercise stress nor caffeine supplementation, and concentrations did not track plasma Hsp72 concentration.
