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.

Abstract

aims/hypothesisSevere hypoglycaemia events (SHE) remain frequent in people with type 1 diabetes despite advanced diabetes technologies. We examined whether time below range (TBR) 3.9 mmol/l (70 mg/dl; TBR70) or 3.0 mmol/l (54 mg/dl; TBR54) is associated with future SHE risk and whether impaired awareness of hypoglycaemia (IAH) modifies this relationship.

methodsWe analysed data from participants in the Study of the French-speaking Society of Type 1 Diabetes (SFDT1) who used continuous glucose monitoring. IAH was assessed using the Gold Score (≤2, no IAH; 3, undetermined; ≥4, IAH). SHE frequency was self-reported 12 months after inclusion. We analysed associations between TBR and SHE using logistic regression models adjusted for age, sex, social vulnerability and insulin treatment, including TBR-IAH interactions. We performed spline analyses to explore non-linear patterns.

resultsOne-year incidence of SHE was 11.7% among 848 participants (mean ± SD age 41.6 ± 13.3 years; 53.8% female sex, HbA CONCLUSIONS/

interpretationTBR alone is not discriminative for high-risk SHE but combining TBR with hypoglycaemia awareness status identifies those at the highest risk for both TBR70 and TBR54.
