Neuroprotective effects of carvedilol in diabetic rats: prevention of defective peripheral nerve perfusion and conduction velocity.
Article in Naunyn-Schmiedeberg's archives of pharmacology, 1995. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The effects of carvedilol (10 mg kg-1 day-1), a peripheral vasodilator and oxygen free radical scavenger, on nerve conduction and blood flow were examined in streptozotocin-diabetic rats. Rats were treated from induction of diabetes for 1 month in a preventive experiment; effects of treatment in non-diabetic rats were also examined. Diabetes caused a 20.0% (P < 0.001) reduction in sciatic motor conduction and a 14.7% (P < 0.001) deficit in saphenous sensory conduction. Diabetic rats given carvedilol treatment had motor and sensory conduction velocities which did not differ significantly from those of non-diabetic controls, but were greater than for untreated diabetes (P < 0.001). Carvedilol treatment did not significantly alter nerve conduction in non-diabetic rats. The nutritive (capillary) component of sciatic endoneurial blood flow, measured by microelectrode polarography and hydrogen clearance, was 45.8% (P < 0.001) reduced by diabetes. This was completely corrected (P < 0.001) by carvedilol treatment in diabetic rats, flow being in the upper half of the non-diabetic range. In non-diabetic rats, carvedilol caused a 30.6% (P < 0.05) elevation in blood flow. Hydrogen clearance data also revealed a shift away from non-nutritive (arterio-venous anastomotic) towards nutritive flow in treated diabetic rats (P < 0.05). We conclude that the data support a neurovascular hypothesis of diabetic neuropathy. Carvedilol, via vasodilator and anti-oxidant actions, prevents the nutritive blood flow changes that lead to nerve dysfunction.(ABSTRACT TRUNCATED AT 250 WORDS)
