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
purposeColorectal cancer (CRC) remains a major global health concern, necessitating innovative therapeutic strategies to enhance treatment efficacy. In this study, we investigated the role of AKR1C4 in CRC and its impact on chemotherapy response.
methodsAKR1C4 stable knockout CRC cell lines were generated using CRISPR/Cas9 technology. The impact of AKR1C4 depletion on chemotherapy sensitivity was assessed using Sulforhodamine B assay. Long-term, low-dose drug induction with increasing concentrations of 5FU, irinotecan, and oxaliplatin were employed to establish acquired chemoresistant CRC cell lines. Ferroptosis induction and inhibition were examined through total iron content and lipid peroxidation measurements.
resultsWe found that AKR1C4 knockout enhances CRC cell sensitivity to chemotherapy, specifically by inducing ferroptosis. The enzymatic activity of AKR1C4 is crucial for regulating chemotherapy sensitivity in CRC cells, as evidenced by the inability of a Y55A mutant to reverse the sensitizing effect. Additionally, AKR1C4 inhibitors enhance chemotherapy sensitivity by inducing ferroptosis. Notably, AKR1C4 depletion resensitizes the acquired chemoresistant CRC cells to chemotherapy, suggesting its potential as a therapeutic target for overcoming acquired chemoresistance. Clinical analysis reveals that high AKR1C4 expression is associated with poor prognosis in CRC patients undergoing chemotherapy, highlighting its significance as a prognostic marker and a potential target for therapeutic intervention.
conclusionThis study illuminates the multifaceted role of AKR1C4 in CRC, demonstrating its significance in regulating chemotherapy sensitivity, overcoming acquired resistance, and impacting clinical outcomes. The insights provided may pave the way for novel therapeutic strategies in CRC management.
