Associations of early pregnancy high-sensitivity C-reactive protein levels with subsequent gestational diabetes: A Finnish gestational diabetes study.

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
backgroundHigh sensitivity C-reactive protein (hsCRP) is a sensitive marker of subclinical inflammation and has been proposed as a marker for predicting gestational diabetes in early pregnancy. However, data concerning the levels of hsCRP in early pregnancy are inconsistent. We aimed to determine hsCRP levels in early pregnancy and to examine the associations between hsCRP levels and the number of abnormal values in the oral glucose tolerance test and the type of hyperglycemia.
methodsEarly pregnancy serum hsCRP levels were analyzed in 776 women with gestational diabetes and 856 pregnant controls without diabetes. The mean gestational age at sampling was 10.7 weeks.
resultsEarly pregnancy hsCRP levels were higher in women who later developed gestational diabetes compared to controls (geometric mean 3.71 mg/L vs. 2.62 mg/L). After adjustments, including those for maternal age and pre-pregnancy body mass index, the results remained significant. When compared to the lowest quartile of hsCRP, women in the other quartiles had 1.5-fold odds for gestational diabetes after adjustments. Furthermore, hsCRP levels were higher in women with two or three abnormal oral glucose tolerance test values compared to those with one abnormal value and among women with postprandial hyperglycemia compared to those with only fasting hyperglycemia.
conclusionEarly pregnancy serum hsCRP levels were associated with subsequent gestational diabetes, and most with a higher number of abnormal values and postprandial hyperglycemia in the oral glucose tolerance test. These findings highlight the role of chronic inflammation and clustering of metabolic risk factors involved in gestational diabetes and its severity.
