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
Radiation resistance has always been one of the main obstacles to tumor radiotherapy. Therefore, understanding the mechanisms underlying radiotherapy resistance is a focus of research. In this study, we induced two radiation-resistant cell lines to mimic the radiation resistance of NSCLC and investigated the mechanisms of radiotherapy resistance. Cell radiosensitivity was analyzed by single-cell gel electrophoresis, colony formation and tumor sphere formation assays. A wound healing assay was used to analyze cell migration. Western blotting and siRNA were used to identify the potential mechanism. In animal model experiments, xenograft tumors were used to verify the difference between radiotherapy-resistant and nonresistant NSCLC models after radiotherapy. Our results showed that NSCLC radiation-resistant cells exhibited more radioresistance and migratory abilities under low-dose irradiation. The expression of LIMK2 and p-CFL1 were upregulated in NSCLC radiation-resistant cells. Knockdown of LIMK2 significantly enhanced the radiosensitivity of NSCLC-resistant cells. In vivo, low-dose radiotherapy suppressed tumor growth, induced apoptosis and upregulated the expression of LIMK2 in xenograft tumors. However, radiotherapy had little effect on the NSCLC radiation resistance model. In conclusion, NSCLC radiation-resistant cells exhibit more radioresistance and migratory ability under low-dose irradiation. Strikingly, knockdown of LIMK2 enhanced the radiosensitivity of NSCLC-resistant cells.
