What This Study Did, in Plain Language
What Was Tested
This randomized controlled trial looks at Insulin Lispro and NPH Insulin (isophane).
To determine insulin kinetics and overnight glycemic control after bedtime administration of a new intermediate-acting insulin preparation called neutral protamine lispro (NPL).
Who Took Part
According to the abstract, 12 patients were involved.
The age groups tagged for this paper are adults and middle-aged adults, both men and women.
How the Study Was Run
The design is described as randomized, double-blind and crossover.
Because people in this Insulin Lispro study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.
As a double-blind Insulin Lispro study, the assignments were hidden from both participants and investigators until the end.
In the crossover set-up each of the patients took both Insulin Lispro and the comparison in turn, acting as their own control.
The study had a double-blind, randomized, crossover design.
What Was Measured
Topics PubMed links to this paper include Blood Glucose, Circadian Rhythm, Diabetes Mellitus, Type 1, Drug Combinations, Glucose Clamp Technique, Hypoglycemic Agents and Insulin.
What This Means in Plain Language
The paper is a randomized, double-blind and crossover study of Insulin Lispro and NPH Insulin (isophane) in 12 patients.
With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.
Its findings take up roughly 4 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.
The publication is from 1997 (Diabetes care), a journal based in United States.

Our Notes on the Compounds
Insulin Lispro: A rapid-acting mealtime insulin analog; brands include Humalog, Admelog and Lyumjev.
NPH Insulin (isophane): An intermediate-acting insulin made by combining insulin with protamine; also called isophane or NPH insulin (Humulin N, Novolin N).
