Utility of Continuous Glucose Monitors for Improved Detection of Cystic Fibrosis-Related Diabetes.

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
backgroundCystic fibrosis-related diabetes (CFRD) can be associated with decline in pulmonary function and nutritional status. Earlier diagnosis of CFRD than offered by annual recommended oral glucose tolerance test (OGTT) and earlier initiation of insulin may help prevent clinical decline. This retrospective study investigates the utility of continuous glucose monitoring (CGM) for detection of hyperglycemia in patients with cystic fibrosis (CF).
methodsIn this single-center, retrospective study, we analyzed data from 18 patients with CF over age 10 who had an abnormal OGTT and subsequently had at least 24 h of CGM data. EasyGV software was used to calculate multiple measures of CGM variability. Differences in OGTT and CGM measures were explored across four glucose-tolerance groups: indeterminate, fasting hyperglycemia, impaired glucose tolerance (with or without fasting hyperglycemia), and CFRD.
resultsMultiple CGM measures correlated with components of the OGTT. Across glucose-tolerance groups, significant differences were observed for the OGTT 2-h glucose (p = 0.002), mean of daily differences from CGM (p = 0.03), and standard deviation from CGM (p = 0.02). Approaching significance was the lability index (p = 0.05) from the CGM data. Glucose management indicator (GMI), continuous overlapping net glycemic action (CONGA), glycemic risk assessment in diabetes equation (GRADE), and average daily risk range (ADRR) showed negative correlations with change in forced expiratory volume over 1 s (FEV1) over the year before OGTT.
conclusionMarkers of glycemic variability may be important variables distinguishing between degrees of abnormal glucose tolerance, including CFRD. This area warrants further research with a larger sample size.
