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

introductionMean platelet volume (MPV), which reflects platelet size and activity, is known to be elevated in patients with type 2 diabetes mellitus. Although increased MPV has been linked to poor glycemic control and diabetic vascular complications, evidence regarding its association with hard kidney outcomes remains limited. We aimed to investigate the relationship between MPV and kidney events in patients with type 2 diabetes mellitus. MATERIALS AND

methodsWe retrospectively analyzed longitudinal data from 1,076 Japanese patients with type 2 diabetes mellitus enrolled in the Fukushima Cohort Study. Participants were categorized into quartiles based on baseline MPV levels. The primary endpoint was kidney events, defined as a ≥50% decline in estimated glomerular filtration rate (eGFR) from baseline or progression to end-stage kidney disease requiring kidney replacement therapy. The secondary endpoint was new-onset cardiovascular events.

resultsDuring a median follow-up of 5.3 years, 97 patients experienced kidney events. The second quartile (Q2) had the lowest incidence of kidney events. Compared with Q2 as the reference, patients in the highest quartile (Q4) had a significantly increased risk of kidney events (adjusted hazard ratio 2.05, 95% confidence interval 1.13-3.72). Higher MPV levels were also significantly associated with an increased risk of cardiovascular events.

conclusionElevated MPV was independently associated with both kidney and cardiovascular events in Japanese patients with type 2 diabetes mellitus. MPV may serve as a simple and useful biomarker for predicting kidney disease progression in this high-risk population.
