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
Objective: The chemotherapy resistance genes in breast cancer are closely related to prognosis. This study is aimed at exploring the key genes that may be involved in chemotherapy resistance of breast cancer and establishing a prognostic model. Methods: Using data from the GEO database, differentially expressed genes (DEGs) related to chemotherapy resistance in breast cancer were identified. Univariate and multivariate Cox regression were used to identify the association between DEGs and prognosis. Subsequently, functional analysis was conducted to characterize the functions of DEGs. In addition, immune-related analysis was performed to study the functions of these hub genes. LASSO-Cox regression analysis narrowed the range of hub genes. A DRFS prognostic nomogram model was constructed using the hub genes. A total of 60 breast cancer patients from the Second Affiliated Hospital of Fujian Medical University were selected as the external validation set. Results: By comparing the gene expression profiles of the Rx_Insensitive group and the Rx_Sensitive group, 162 DEGs were screened out, among which 53 DEGs were upregulated and 109 DEGs were downregulated. Univariate Cox regression analysis of the 162 DEGs with survival showed that GREB1, DACH1, STAP1, TDRD12, and SCGB1D2 were significantly associated with prognosis (all Conclusions: The prognostic model developed based on the five breast cancer chemotherapy resistance-related genes (GREB1, DACH1, STAP1, TDRD12, and SCGB1D2) has good predictive performance for BRCA patients.
