Low prevalence of GCK gene mutations in Chinese patients with gestational diabetes mellitus.

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
BACKGROUND AND
aimAccumulating evidence suggests maturity onset diabetes of the young (MODY) caused by GCK gene mutations (GCK-MODY) is often misdiagnosed as Gestational Diabetes Mellitus (GDM) in pregnant women. This study investigated the prevalence and diagnostic value of GCK gene mutations in Chinese GDM patients.
methodsA retrospective analysis was conducted on 3394 pregnant women undergoing prenatal care or delivery at Beijing Jishuitan Hospital between April and December 2019. GDM was diagnosed in 474 women (14.0%) using the International Association of Diabetes and Pregnancy Study Groups (IADPSG, 2010) criteria via a 75 g Oral Glucose Tolerance Test (OGTT). Among these, 177 GDM patients with fasting blood glucose ≥5.1 mmoL/L underwent targeted GCK gene sequencing.
resultsTargeted sequencing identified eight rare GCK variants in nine individuals. None of the variant carriers met definitive diagnostic criteria for GCK-MODY. The prevalence of rare GCK variants in the screened GDM subgroup was 1.9% (9/474).
conclusionThe low prevalence (1.9%) of rare GCK variants and absence of confirmed GCK-MODY cases indicate limited utility of fasting glucose-based screening for GCK-MODY in Chinese GDM populations. These findings highlight challenges in distinguishing GCK-MODY from GDM through conventional glucose thresholds.
