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

BACKGROUND AND

aimSodium-glucose cotransporter-2 (SGLT2) inhibitors, glucose-lowering drugs that increase urinary glucose excretion have been shown to reduce CV events in patients with type 2 diabetes (T2D). Furthermore, several studies have demonstrated that treatment with SGLT2 inhibitors affect calcium and phosphate homeostasis, but the effect of empagliflozin on these biomarkers is hitherto not investigated in detail. Therefore, this analysis of the EMPA hemodynamics study examined effects of empagliflozin on calcium and phosphate homeostasis.

methodsIn this placebo-controlled, randomized, double-blind study patients with T2D were randomized to empagliflozin 10 mg (n = 20) or placebo (n = 22). Biomarkers of calcium and phosphate homeostasis were assessed before, and after 3 days and 3 months of treatment.

resultsAfter 3 days of treatment empagliflozin significantly increased serum levels of phosphate (baseline: 1.10 ± 0.21 mmol/L; day 3: 1.25 ± 0.23 mmol/L; p = 0.036), parathyroid hormone (PTH) (baseline: 57.40 ± 30.49 pg/mL; day 3: 70.23 ± 39.25 pg/mL; p = 0.025), fibroblast growth factor 23 (FGF23) (baseline: 77.92 ± 24.31 pg/mL; day 3: 109.18 ± 58.20 pg/mL; p = 0.001) and decreased 1,25-dihydroxyvitamin D (baseline: 35.01 ± 14.01 ng/L; day 3: 22.09 ± 10.02 mg/L; p < 0.001), while no difference of these parameters was recorded after 3 months of treatment. Empagliflozin had no significant effects on serum calcium and markers of bone resorption (collagen type 1 β-carboxy-telopeptide = β-CTX) or formation (osteocalcin) after 3 days and 3 months of treatment.

conclusionsEmpagliflozin treatment of patients with T2D transiently increases serum phosphate, PTH and FGF23, and decreases 1,25-dihydroxyvitamin D. This might reflect a temporal increase of sodium driven phosphate reabsorption in the proximal tubule of the kidney caused by increased sodium availability in response to SGLT2 inhibition.
