Tetramethylpyrazine and renal ischemia-reperfusion injury: a systematic review and meta-analysis of preclinical studies.

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
Objectives: The aim of this systematic review and meta-analysis is to synthesize the effects and mechanisms of Tetramethylpyrazine (TMP) on renal outcomes in animal models of renal I/R injury. Methods: Animal studies from seven electronic databases were searched up to October 2024. The risk of bias of the selected studies was assessed using the SYRCLE risk of bias tool. Standardized mean difference (SMD) or mean difference (MD) were estimated for the effects of TMP on serum creatinine (Scr), blood urea nitrogen (BUN), oxidative stress, inflammation and apoptotic. Random-effects models were used to summarize results. Heterogeneity was expressed as I Results: Thirty studies involving 559 animals were identified for analysis. TMP treatment significantly decreased Scr (SMD = 2.35, 95% CI: -2.97 to -1.72, P < 0.05), BUN (SMD = -2.4, 95% CI: -3.01 to -1.79, P < 0.05). TMP treatment significantly improved oxidative stress expression (i.e., SOD, MDA, GSHPX, CAT, TAC) and alleviated inflammation levels (i.e., TNF-α, ICAM-1, IL-6, IL-10, NLRP3). TMP treatment also regulate the expression of apoptosis-related proteins (i.e., bcl-2, Bax, caspase 3, Caspase-12 and GRP78). Conclusion: TMP could improve renal outcomes and alleviate injury through multiple signaling pathways. However, positive results should be treated with caution due to the significant heterogeneity and poor quality of the included studies. Systematic Review Registration: CRD420251017081.
