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
Autophagy is an evolutionarily conserved process that cells use to degrade and recycle cellular proteins and remove damaged organelles. During the past decade, there has been a growing interest in defining the basic cellular mechanism of autophagy and its roles in health and disease. However, the functional role of autophagy in kidney fibrosis remains poorly understood. Here, using GFP-LC3 transgenic mice, we show that autophagy is induced in renal tubular epithelial cells (RTECs) of obstructed kidneys after unilateral ureteral obstruction (UUO). Deletion of LC3B (LC3(-/-) mice) resulted in increased collagen deposition and increased mature profibrotic factor TGF-β levels in obstructed kidneys. Beclin 1 heterozygous (beclin 1(+/-)) mice also displayed increased collagen deposition in the obstructed kidneys after UUO. We also show that TGF-β1 induces autophagy in primary mouse RTECs and human renal proximal tubular epithelial (HK-2) cells. LC3 deficiency resulted in increased levels of mature TGF-β in primary RTECs. Under conditions of TGF-β1 stimulation and autoinduction, inhibition of autolysosomal protein degradation by bafilomycin A1 increased mature TGF-β protein levels without alterations in TGF-β1 mRNA. These data suggest a novel intracellular mechanism by which mature TGF-β1 protein levels may be regulated in RTECs through autophagic degradation, which suppresses kidney fibrosis induced by UUO. The dual functions of TGF-β1, as an inducer of TGF-β1 autoinduction and an inducer of autophagy and TGF-β degradation, underscore the multifunctionality of TGF-β1.
