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
objectivesExcessive production of AGEs in diabetic patients will affect the normal function of osteoblasts, and this process may be related to autophagy of osteoblasts. This study aims to explore the effect of advanced glycation end products (AGEs) on autophagic activity during osteogenic differentiation in rat bone marrow mesenchymal stem cells (BMSCs).
methodsBMSCs were isolated and cultured in vitro, treated with different concentrations (0, 50, 100, 200, and 400 mg/L) of AGEs for different time (3, 6, 12, 24, 48, and 72 h). The proliferation activity was detected by CCK-8 method. The mRNA and protein expression levels of Beclin1 and LC3 in cells were detected by real-time PCR and Western blotting, respectively.The autophagic vacuoles were observed under the transmission electron microscope. The cells were treated with autophagy promoter rapamycin or autophagy inhibitor 3MA. After 7 days of osteogenic induction, we performed alkaline phosphatase (ALP) staining and real-time PCR to detect the mRNA expression levels of osteogenesis-related genes.
resultsIn the low-concentration groups, the proliferation activity in BMSCs was increased (
conclusionsLow concentration of AGEs can enhance the proliferative activity of BMSCs and promote osteogenic differentiation by accelerating autophagy. High concentration of AGEs can suppress the proliferation of BMSCs and inhibit osteogenic differentiation by reducing autophagy.
