1 · What the graph read from it

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.

2 · The registry

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

backgroundPatients with latent autoimmune diabetes in adults (LADA) share overlapping clinical phenotypes with Type 2 diabetes mellitus. Extended autoimmune phenotype confirmation intervals and higher complication risks are observed alongside this phenotypic overlap. Real-world epidemiological data characterizing this interval and relevant clinical indicators remain scarce for Southwest China. This study is aimed at quantifying the duration of this interval and identifying clinical indicators of prolonged confirmation intervals among hospitalized patients in this understudied region.

methodsThis multicenter retrospective cross-sectional study recruited consecutive inpatients with confirmed LADA from tertiary hospitals across Southwest China between January 2019 and June 2025. Standardized extraction of baseline demographic, clinical, and laboratory data was performed from electronic medical records. The primary binary outcome was defined as the confirmation interval from initial diabetes diagnosis to autoimmune serological testing, which was dichotomized to distinguish patients with prolonged confirmation intervals. Multivariable binary logistic regression was used to identify clinical indicators showing synchronous coexistence with the intervals. The area under the curve (AUC) and Hosmer-Lemeshow goodness-of-fit test were adopted to evaluate the discrimination and calibration of the regression model.

resultsA total of 578 eligible participants were included, among whom 363 (62.8%) presented prolonged confirmation intervals. The median interval was 2 (0, 7) years across the overall cohort and 5 (2, 10) years for the prolonged-interval group. The multivariate regression model showed satisfactory goodness-of-fit. Seven clinical indicators of prolonged confirmation intervals were divided into three categories: demographic and behavioral characteristics including educational level and duration of alcohol consumption; metabolic biomarkers measured at LADA confirmation including inpatient mean blood glucose and 2-hour C-peptide levels; advanced diabetic manifestations including diabetic retinopathy, diabetic ketosis, and polypharmacy.

conclusionsA substantial proportion of hospitalized LADA patients in Southwest China present prolonged autoimmune confirmation intervals. Seven clinical indicators showing stable synchronous coexistence with the intervals were identified. The findings provide region-specific real-world evidence characterizing clinical features of patients with such intervals to guide inpatient clinical management. Multicenter prospective studies enrolling community populations are required to examine whether these synchronously coexisting indicators apply to broader patient groups.
