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
Intratumoral heterogeneity of breast cancer cells causes undesired drug resistance and predispose to disease recurrence. We investigate the molecular heterogeneity of breast cancer cells derived from malignant pleural effusions (MPE) to understand variations in drug resistance and cellular evolution. MPE provides a unique environment, with cells experiencing significant microenvironmental changes that promote intratumoral heterogeneity and therapeutic resistance. By establishing 24 cell lines and 3 organoids from MPE samples of breast cancer patients, we performed extensive genomic, transcriptomic, and drug sensitivity analyses. Our findings reveal substantial genetic and transcriptomic diversity among MPE-derived cell lines, highlighting dynamic alterations in driver mutations and signaling pathways that correlate with variable drug responses. Notably, temporal and spatial heterogeneity within patient-derived samples emphasized the adaptability of breast cancer cells in MPE, as different subclones displayed distinct drug sensitivities. This work underscores the critical role of molecular profiling in understanding treatment resistance in breast cancer, presenting MPE-derived cell lines as valuable preclinical models for exploring personalized therapies in aggressive cancer phenotypes.
