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

aims5α-Reductase inhibitors are prescribed for the treatment of benign prostatic hyperplasia (BPH) and their use is associated with increased risk of incident type 2 diabetes. This study assessed the long-term cardiovascular safety of 5α-reductase inhibitors in comparison with tamsulosin in people with co-existing BPH and type 2 diabetes. METHODS AND

resultsWe performed a retrospective, population-based cohort study using Scottish Diabetes Research Network National Diabetes Dataset (SDRN-NDS) and IQVIA Medical Research Data (IMRD-UK). BPH patients ≥40 years with recorded type 2 diabetes mellitus and ≥2 prescriptions of 5α-reductase inhibitors or tamsulosin (2006-2021) were included. After 1:2 variable ratio propensity score matching, cause-specific Cox proportional-hazard models were used to compute the hazard ratio (HR) of incident major adverse cardiovascular events (MACE). A total of 11 969 patients were included in SDRN-NDS and 16 492 in IMRD-UK, with median follow-up durations of 3.8 (IQR: 1.7-6.8) and 4.8 (2.0-8.3) years, respectively. In SDRN-NDS, the HR of MACE in patients receiving 5α-reductase inhibitors relative to tamsulosin was 1.15 (95% CI 1.03-1.30, P = 0.007), driven by increased risk of myocardial infarction (MI) (HR 1.20, 1.03-1.40, P = 0.022). This was replicated in IMRD-UK, where HR was 1.26 (1.07-1.47, P = 0.008) for MACE and 1.33 (1.10-1.60, P = 0.005) for MI. We did not observe any increased risks in stroke, cardiovascular death, microvascular complications of diabetes, or faster progression to insulin-based therapies.

conclusionOur retrospective data from two large cohorts suggest that the risk of MACE may be increased among patients with type 2 diabetes taking 5α-reductase inhibitors, potentially driven by increased risk of MI. This supports careful monitoring of macrovascular outcomes when prescribing 5α-reductase inhibitors in this population.
