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
Glomerular mesangial cell (GMC) senescence contributes to the progression of various age-related kidney diseases. However, the molecular mechanisms driving GMC aging remain poorly understood. OIP5-AS1, a long non-coding RNA (lncRNA), has been implicated in cellular senescence in other systems, but its role in renal aging remains unclear. This work aimed to elucidate the functional role and underlying mechanism of OIP5-AS1 in GMC senescence. A D-galactose (D-gal)-induced senescence model was established in both mouse kidneys and SV40-MES13 mesangial cells. RT-qPCR was performed to quantify the levels of OIP5-AS1, ELAVL1, and HMGB1, while CCK-8 assays assessed cellular metabolic activity. Cellular senescence was evaluated using SA-β-gal staining, and the expression of senescence-associated proteins (p16, p21, p53) was quantified by Western blot analysis. Levels of SASP-related cytokines, including IL-6, IL-1β, TNF-α, and IL-18, were measured via ELISA. To explore the underlying mechanism, RNA pull-down and RIP assays were performed to investigate the interactions among OIP5-AS1, ELAVL1, and HMGB1, while actinomycin D assays were used to evaluate HMGB1 mRNA stability. OIP5-AS1 expression was markedly elevated in renal tissues and GMCs following D-gal-induced senescence. Knockdown of OIP5-AS1 alleviated cellular senescence. Mechanistically, OIP5-AS1 directly interacted with ELAVL1, thereby stabilizing HMGB1 mRNA and promoting HMGB1 expression. Rescue experiments further confirmed that ELAVL1 and HMGB1 mediated OIP5-AS1-induced GMC senescence. LncRNA OIP5-AS1 promotes GMC senescence by interacting with ELAVL1 to upregulate HMGB1.
