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

backgroundSodium-glucose co-transporter 2 (SGLT2) inhibitors are important for treating patients with preserved left ventricular (LV) ejection fraction (LVEF). Several studies have assessed the effects of SGLT2 inhibitors on LV diastolic function, with conflicting results. In this sub-analysis of the Program of Ipragliflozin for Endothelial Dysfunction in Chronic Kidney Disease and Type 2 Diabetes (PROCEED) trial-including patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD)-we examined the effect of ipragliflozin compared with non-SGLT2 inhibitor standard therapy (control) on changes in the maximum early diastolic velocity to average early diastolic peak velocity (E/e') ratio (an index of LV diastolic function) via echocardiography.

methodsOf the entire PROCEED trial dataset, 57 participants (ipragliflozin group, n = 28; control group, n = 29) with available echocardiography data at baseline and 24 weeks were included. The primary endpoint was the change in the E/e' ratio from baseline to 24 weeks. The effect of SGLT2 inhibitors on the endpoint was stratified by baseline LVEF, body mass index (BMI), N-terminal pro-brain natriuretic peptide (NT-proBNP) level, estimated glomerular filtration rate (eGFR), and urine albumin-to-creatinine ratio (UACR).

resultsNo significant difference in the E/e' ratio changes was observed between the ipragliflozin and control groups (group difference: - 0.82 [95% CI: - 2.44 to 0.81]; P = 0.317). The E/e' ratio was unaffected by baseline NT-proBNP, eGFR, and UACR levels. However, ipragliflozin significantly reduced the E/e' ratio in patients with LVEF ≥ 60% (n = 21, group difference: - 1.42 [- 2.76 to - 0.08]; P = 0.038) or BMI ≥ 25 kg/m

conclusionsIn subgroups with higher LVEF and BMI, ipragliflozin improved diastolic function more than standard treatment. These results may partly support the beneficial effect of SGLT2 inhibitors on LV diastolic performance.
