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
The objective of our study was to use quantum dots for the purpose of seeing and detecting C-C motif chemokine ligand 5 (CCL5) inside the tissue of sentinel lymph nodes (SLN) and primary tumors. This endeavor aimed to enhance the accuracy of predicting the condition of non-sentinel lymph nodes and provide valuable insights for making informed treatment choices. We analyzed breast cancer patients who underwent sentinel lymph node biopsy followed by axillary lymph node removal due to one or two positive sentinel lymph nodes at the Second People's Hospital of Wuhu, China, between August 2018 and July 2022. Quantum dot technology was employed to visualize and determine CCL5 in the tissue samples from 84 patients. Out of a group diagnosed with breast cancer, 208 underwent sentinel lymph node biopsy. From this pool, 84 tested positive and subsequently underwent axillary lymph node removal. The presence of distinct orange-red fluorescence, linked to quantum dots, was evident in the cellular components of both primary tumors and positive sentinel lymph node tissues. We found a significant relationship between higher levels of SLNCCL5 and advanced tumor growth (P < 0.05). To understand the predictive value of SLN CCL5 related to non-sentinel lymph node status, we utilized the receiver operating characteristic (ROC) method. The area under the curve (AUC) calculated was 0.745 with a cutoff point of 23.285. Multivariate logistic regression was used to understand the effect of tumor dimensions and SLNCCL5 levels on non-sentinel lymph node status in specific patients. Both the size of the tumor and SLNCCL5 levels were found to have a significant impact (P < 0.05). Data suggested that the presence of positive SLNCCL5 might serve as an assessment parameter for anticipating the condition of non-SLN in cases of breast cancer involving T1 or T2 tumors with one or two positive sentinel lymph nodes.
