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

introductionDespite the increasing number of studies using machine learning to develop individualized treatment strategies, only a few have been conducted in patients with type 1 diabetes. This study aimed to identify the characteristics of Japanese patients with type 1 diabetes, classified into subgroups using data-driven cluster analysis based on pancreatic beta-cell function, obesity, and glycemic control, and clarify the association between these subgroups and diabetic complications. MATERIALS AND

methodsIn this cross-sectional study, a cluster analysis using three variables (C-peptide, body mass index, and glycated hemoglobin) in 206 Japanese patients with type 1 diabetes was performed. Multivariate logistic regression analysis was performed to compare the risk of diabetic complications by subgroup.

resultsThe cluster analysis identified four subgroups. Group 2 (n = 58), characterized by high body mass index levels, had a higher risk of hepatic steatosis than the control group (Group 1, n = 90). Meanwhile, Group 3 (n = 44), characterized by high glycated hemoglobin levels, had higher risks of retinopathy, polyneuropathy, elevated brachial-ankle pulse wave velocity, and hepatic steatosis than Group 1 and Group 4 (n = 14), characterized by residual endogenous insulin, had a higher risk of chronic kidney disease than Group 1.

conclusionsThe risks of diabetic complications differed between subgroups of Japanese patients with type 1 diabetes. Tailored treatment approaches based on subgroup characteristics are a potential treatment option for reducing the risks of diabetic complications in this population.
