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

objectivesTo assess the association between sodium-glucose co-transporter-2 inhibitor (SGLT-2i) use and the risk of incident dementia compared with dipeptidyl peptidase-4 inhibitors (DPP-4i) use among individuals with type 2 diabetes.

designA population-based retrospective cohort study.

settingThe Clinical Practice Research Datalink (CPRD) Aurum database from the UK.

participantsIndividuals with type 2 diabetes, aged 40 years or older, newly prescribed SGLT-2i or DPP-4i on or after 2013-2021, registered in the CPRD Aurum database.

main outcome measureThe primary outcome was incident dementia, and the secondary outcome was incident mild cognitive impairment (MCI). Cox proportional hazard models were used to estimate the HR and corresponding 95% CI for the primary and secondary outcomes. Propensity score fine stratification weights were used to adjust for confounding.

resultsAmong a cohort of 118 006 individuals, the incident rate (IR) of dementia was 0.56/1000 person-years over a median follow-up period of 1.54 years among SGLT-2i users compared with 2.67/1000 person-years in DPP-4i users, over a median follow-up period of 1.79 years. The adjusted HR for SGLT-2i use compared with DPP-4i use for dementia was 0.78 (95% CI 0.55 to 1.12), while for MCI was 0.86 (95% CI 0.80 to 0.92). The age-specific stratified analysis demonstrated the adjusted HR for SGLT-2i use compared with DPP-4i use for the risk of incident dementia among elderly, aged ≥65 years, was 0.50 (95% CI 0.31 to 0.80).

conclusionPrimary findings did not yield conclusive evidence to infer an association between SGLT-2i use and the risk of incident dementia.
