Nitric oxide and noradrenaline contribute to the temperature threshold of the axon reflex response to gradual local heating in human skin.
Trial report in The Journal of physiology, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02549534 (Early Detection of Taxane-Induced Neuropathy in Women With Breast Cancer), which is not on this map. Cited by 53 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.

Abstract
The initial skin blood flow response to rapid local heating is an axon reflex, which may be mediated by calcitonin gene-related peptide and substance P released from C-fibres. We investigated the role of nitric oxide (NO) and noradrenaline on the temperature threshold for the axon reflex during gradual local heating. 36 subjects participated in two studies. Using microdialysis, we examined the following interventions: NO synthase inhibition (10 mM N(G)-nitro-L-arginine methyl ester, L-NAME); low-dose NO infusion (1.0 microM sodium nitroprusside, SNP); adrenergic blockade (10 mM bretylium tosylate); and low-dose (0.1 microM) noradrenaline infusion. Laser-Doppler flowmetry was used to measure red blood cell flux. Skin was heated at a rate of 0.1 degrees C min(-1) from 33 degrees C to 40 degrees C. Compared to control skin sites, the axon reflex response was shifted to a higher temperature in 4 subjects in the L-NAME sites (control, 37.0 +/- 0.3 degrees C, n = 16; L-NAME, 39.8 +/- 0.1 degrees C, n = 4; P < 0.001) and absent in 12 subjects. The response was also absent in L-NAME plus low-dose SNP sites and not altered by low-dose SNP infusion alone. Adrenergic blockade, with and without low-dose noradrenaline infusion, also abolished the axon reflex response in all subjects. Low-dose noradrenaline infusion alone shifted the axon reflex to a significantly lower temperature threshold compared to control sites (control, 38.2 +/- 0.5 degrees C; noradrenaline, 37.7 +/- 0.4 degrees C, P < 0.05, n = 5). These results suggest that endogenous NO and noradrenaline contribute to the temperature threshold of the axon reflex response during gradual local heating of the skin.
