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.
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 cotransporter-2 (SGLT-2) inhibitors, as a new type of hypoglycemic drug, can prevent proximal renal tubule injury related to glucose toxicity and play a renoprotective role. Canagliflozin, a recognized SGLT-2 inhibitor, has been proved to have potential protection in diabetic nephropathy (DN), but its mechanism has not been fully elucidated. In this study, the protective effect of canagliflozin against high glucose (HG)-induced renal tubular epithelial cell (NRK-52E) injury in vitro was assessed.
methodsThe viability and apoptosis of NRK-52E cells were detected using cell counting kit-8 (CCK-8) assay and flow cytometry analysis, respectively. The expression levels of cleaved caspase-3, oxidative stress-related proteins (NOX4 and Nrf2), autophagy marker light chain 3 (LC3) I/II, and adenosine monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) signaling pathway-related proteins were evaluated by Western blot. Reactive oxygen species (ROS) level was evaluated by dihydroethidium (DHE) reactive oxygen species assay, the activities of SOD, CAT, GSH-Px and MDA were analyzed using kits. The changes of morphology and red fluorescent protein (RFP)-LC3 fluorescence were observed under microscopy.
resultsCanagliflozin significantly ameliorated HG-induced NRK-52E cell apoptosis and caspase-3 cleavage. Furthermore, canagliflozin markedly ameliorated HG-induced NRK-52E cell oxidative stress. Moreover, canagliflozin significantly increased LC3-II levels and induced RFP-LC3-containing punctate structures in NRK-52E cells. Finally, canagliflozin increased the phosphorylation of AMPK and suppressed the phosphorylation of mTOR. The AMPK inhibitor compound C abolished canagliflozin-induced autophagy activation, as well as the anti-apoptotic effect of canagliflozin.
conclusionCanagliflozin effectively ameliorate HG-induced apoptosis of NRK-52E cells in vitro that involved its antioxidant effect and induction of autophagy through the AMPK/mTOR pathway.
