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

Introduction: Although dapagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, delays the progression of chronic kidney disease (CKD), its effect on patients with autosomal dominant polycystic kidney disease (ADPKD) has not been established. We conducted an open-label, randomized controlled crossover trial to evaluate the additive effects of dapagliflozin in patients with ADPKD receiving tolvaptan. Methods: A total of 27 patients were randomly counterbalanced to receive dapagliflozin 10 mg or usual care without dapagliflozin for 6 months. The primary endpoint was the slope of the estimated glomerular filtration rate (eGFR) determined by linear regression from 1 to 6 months, and the secondary endpoints included changes in total kidney volume (TKV). eGFR was calculated based on creatinine levels (eGFR Results: There were significant attenuations in the eGFR Conclusion: In patients with ADPKD treated with tolvaptan, dapagliflozin may have an additive effect in slowing ADPKD progression.
