Effects of a novel acetaminophen analog on cardiorespiratory compensatory responses and survival in a male rat model of traumatic hemorrhage.

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
When pain is associated with traumatic hemorrhage, medics must be concerned about secondary effects of analgesics on cardiorespiratory systems. A novel analog of acetaminophen, D-112, was developed to circumvent liver toxicity and improve analgesic efficacy. D-112 causes dose-related inhibition of formalin-induced licking. The objective of this study was to test the effects of D-112 on survival and cardiorespiratory variables following hemorrhage and extremity trauma (ET). We hypothesized that D-112 would significantly change cardiorespiratory responses to HEM and thereby decrease survival. Male rats received either vehicle (lactated Ringer's) or D-112 (50 mg/kg) after conscious hemorrhage of either 37% (n = 10, vehicle and D-112) or 50% (n = 8, vehicle; n = 11, D-112) of blood volume following ET, which consisted of soft tissue injury and fibula fracture. Rats were observed for 4 h after the start of hemorrhage. Neither survival times (37% hemorrhage: p = 0.474; 50% hemorrhage: p = 0.306) nor survival curves (37% hemorrhage: p = 0.146; 50% hemorrhage: p = 0.280) differed between treatments. Mean arterial pressure did not differ between treatments (37% hemorrhage: p = 0.742; 50% hemorrhage: p = 0.521). D-112 transiently elevated minute ventilation (p < 0.001) after both hemorrhages. D-112 does not alter cardiorespiratory responses to the point of depressing survival, suggesting that D-112 could be an appropriate analgesic following traumatic hemorrhage.
