Real-time autonomic responses to insulin-induced hypoglycaemia in volunteers with type I diabetes compared to controls.

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
Objective: Hypoglycaemia is a severe risk of insulin-treatment in diabetes, and in type 1 diabetes (T1D), the normal counterregulatory autonomic mechanisms are diminished. This study investigated the recovery of both parasympathetic and sympathetic tone from hypoglycaemia to normoglycemia in T1D in comparison to controls. Methods: Six individuals with T1D without complications and six age and sex-matched controls were included in this explorative acute intervention study. Electrocardiogram, skin blood flow (SBF, sympathetic measure), cardiac vagal tone (CVT, parasympathetic measure), and plasma glucose were measured at baseline, at hypoglycaemia, and at 30-, 60-, 120-, and 240-minutes post-hypoglycaemia. Results: Insulin injection induced hypoglycaemia with a reduction of CVT in both controls and individuals with T1D, but no consistent response in SBF. Normoglycemia was reached by 120-minutes, though T1D showed delayed glucose recovery at 30- and 60-minutes with an overshoot at 240-minutes. SBF showed no consistent changes but was lower in T1D at 240-minutes. CVT increased consistently, recovering after 60-minutes in the individuals with T1D and 30-minutes in the controls, with a heightened at 240-minutes in the individuals with T1D. Conclusion: CVT as a measure of cardiac parasympathetic function responds consistently to both hypoglycaemia and during recovery in individuals with T1D and controls, but SBF as a measure of cutaneous sympathetic function does not. There are defective counterregulatory mechanisms in T1D shown by delayed recovery of blood glucose and rebound overactivity of both cardiac parasympathetic tone and sympathetic cutaneous vasoconstriction.
