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
Osteosarcoma (OS) is a primary malignant bone tumor. Ferroptosis is closely related to the progression of osteosarcoma. The aim of this study is to explore the mechanism of ferroptosis-related genes in the progression of osteosarcoma.
methodsUtilizing the scRNA-seq dataset of osteosarcoma, differentially expressed genes (scRNA-DEGs) were identified between the osteosarcoma group and the control group, and ferroptosis-related genes in the TARGET-OS dataset were identified through WGCNA. By intersecting these two sets of ferroptosis-related genes, key candidate genes related to ferroptosis were obtained. The prognostic genes were selected from key candidate genes through univariate Cox and LASSO regression analysis. A prognostic model based on these genes was then constructed to investigate the relationship between ferroptosis and the prognosis of osteosarcoma patients. The correlation between the prognostic genes and immune cells, as well as immune checkpoint genes, was investigated through immune infiltration analysis. The drugs binding to prognostic genes were predicted.
resultsWe identified 48 ferroptosis-related genes in the scRNA-seq dataset, and 3859 ferroptosis-related genes were identified in the TARGET-OS dataset. After intersecting the two sets, 12 key ferroptosis-related genes were obtained, among which four genes (
