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
Image-guided radiotherapy (IGRT) is a crucial technique in cervical cancer treatment, enabling precise targeting of tumor tissues while minimizing radiation exposure to surrounding healthy tissues. Kilovoltage cone-beam computed tomography (KVCBCT) is commonly used for IGRT, allowing for real-time imaging of tumor position and anatomy during treatment sessions. However, the selection of optimal landmarks for image registration in IGRT remains a topic of investigation. This study investigated role of IGRT in cervical cancer treatment by analyzing eight cervical cancer patients treated at University Hospital between April 2019 and April 2021. All patients underwent KVCBCT IGRT treatment, and initial treatment images were analyzed. Landmarks including bone, coccyx, and tumor regions were selected for image registration with reference images using both automatic and manual registration methods. Correlation was also sought with several non-coding RNAs, particularly miR-21 and miR-34a. The registration results of different landmarks were observed and compared to evaluate their accuracy and reliability. The study revealed that there were no statistically significant differences in positional errors between bone and tumor landmarks in three directions. However, statistically significant differences in positional errors were observed in the XY and Z directions compared to the coccyx landmark. The miRNA levels correlated with documented trends in cervical cancer. These findings suggest that selecting bone and tumor landmarks as optimal registration points for image registration can enhance the effectiveness of IGRT in treating cervical cancer. By employing both automatic and manual registration methods and analyzing the differences in registration results among various landmarks, this study provides insights into the role of IGRT in cervical cancer treatment. The results indicate that choosing bone and tumor landmarks as optimal registration points can improve the accuracy and efficacy of IGRT, leading to better treatment outcomes and reduced side effects. These findings offer scientific evidence and practical guidance for the utilization of IGRT in cervical cancer treatment, providing valuable technical support for future clinical practice.
