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
Previously, we fabricated a device with polylactic acid nonwoven filters and mesenchymal stem cells (MSCs), which effectively reduced urinary protein levels in a rat model of chronic kidney disease (CKD) but could not suppress CKD progression. Therefore, to improve the therapeutic effects of MSCs, in this study, we analyzed the ability of rat adipose tissue-derived MSCs (ADSCs) in contact with chitin nonwoven filters or chitin powder to produce growth factors and examined their therapeutic effect in an adriamycin (ADR)-induced CKD rat model. Hepatocyte growth factor (HGF) and vascular endothelial growth factor (VEGF) production was significantly enhanced by ADSCs cultured in a medium containing chitin powder (C-ADSCs) compared with that by ADSCs cultured in a standard medium without chitin (N-ADSCs). However, the production of HGF and VEGF by ADSCs on chitin nonwoven filters was not significantly enhanced compared with that by the control. Intravenous C-ADSC injection significantly increased podocin expression and improved proteinuria compared with those in saline-treated CKD rats; however, no such improvements were observed in the N-ADSC-treated group. These results showed that ADSCs cultured in a medium supplemented with chitin powder suppressed proteinuria via enhanced HGF and VEGF production in ADR-induced CKD rats to mitigate podocyte damage, offering a new strategy to reduce the dose of MSC therapy for safe and effective treatment of kidney disease.
