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
introductionBreast cancer can be treated effectively with personalized, gene-targeted therapies due to its molecular and genetic differences. Our study aims to identify breast cancer-specific tumor suppressor genes related to autophagic cell death and discover new drugs that target these mechanisms, even if they are not breast cancer-specific. MATERIALS AND
methodsGene intensity values of 457 tumor and 19 healthy breast tissues were used to determine downregulated and upregulated genes related to autophagy and apoptosis using Bioconductor R program via LIMMA package. Then, genes affecting survival were identified by survival analysis via Kaplan-Meier Plotter tool. Furthermore, the signalling pathways associated with these genes and targeting candidate drug components were determined by gene enrichment analysis using “KEGG pathway option” and Drug MATADOR in “ShinyGo 0.82” web-tool, respectively.
resultsBreast cancer tumor tissues showed downregulation of genes related to autophagy and apoptosis (c19orf12, CRYAB, LEP, SRPX, SNCA, FOXO1) and upregulation of others (SLC7A5, ATP2A2, INHBA, ATP5IF1). Among these, SLC7A5, c19orf12, LEP, SPRX, SNCA, and FOXO1 affected patient survival and prognosis. The AMPK signaling pathway, targeting FOXO1 and LEP, was identified as key. Only the LEP gene was targeted by Metformin, Pioglitazone, Rosiglitazone, and Troglitazone.
conclusionIn our study, survival associated LEP and FOXO1 genes were identified as candidate tumor suppressor genes associated with autophagic cell death in non-obese and non-diabetic breast cancer patients. Anti-diabetic drugs such as Metformin, Pioglitazone, Rosiglitazone, Troglitazone are proposed as candidate components in the treatment processes by targeting the LEP gene in nondiabetic breast cancer patients.
