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
purposeAlthough cisplatin-containing chemotherapy has been utilized as a front-line treatment for cervical cancer, intrinsic and acquired resistance of cisplatin remains a major hurdle for the durable and curative therapeutic response. We thus aim to identify novel regulator of cisplatin resistance in cervical cancer cells.
methodsReal-time PCR and western blotting analysis were employed to determine the expression of BRSK1 in normal and cisplatin-resistant cells. Sulforhodamine B assay was conducted to assess the sensitivity of cervical cancer cells to cisplatin. Seahorse Cell Mito Stress Test assay was utilized to evaluate the mitochondrial respiration in cervical cancer cells.
resultsBRSK1 expression was upregulated in cisplatin-treated cervical cancer patient tumors and cell lines compared with untreated tumors and cell lines. Depletion of BRSK1 significantly enhanced the sensitivity of both normal and cisplatin-resistant cervical cancer cells to cisplatin treatment. Moreover, BRSK1-mediated regulation of cisplatin sensitivity is conducted by a subpopulation of BRSK1 residing in the mitochondria of cervical cancer cells and is dependent on its kinase enzymatic activity. Mechanistically, BRSK1 confers cisplatin resistance via the regulation of mitochondrial respiration. Importantly, treatment with mitochondrial inhibitor in cervical cancer cells phenocopied the BRSK1 depletion-mediated mitochondria dysfunction and cisplatin sensitization. Of note, we observed that high BRSK1 expression is correlated with poor prognosis in cisplatin-treated cervical cancer patients.
conclusionOur study defines BRSK1 as a novel regulator of cisplatin sensitivity, identifying that targeting BRSK1-regulated mitochondrial respiration could be a useful approach for enhancing the efficacy of cisplatin-based chemotherapy in cervical cancer patients.
