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
Introduction: The purpose of this research was to explore the correlation between Gleason score and pattern and the expression of the MLH1, MSH2, MDC1, TP53BP1 proteins in prostate cancer (PC). Prostate cancer development is related to errors in DNA, among others double-strand breaks (DSB) and changes in the base sequence of the DNA. These errors should be repaired through mismatch (MMR) or DSB repair proteins such as MSH2, MLH1, MDC1 and TP53BP1. Material and methods: A total of 500 prostate cancer specimens were recruited in this study. From among all gathered specimens the 52 most suitable cases were selected. The expression of examined proteins was detected by immunohistochemistry, and its correlation with the Gleason score and pattern were further analyzed through standard statistical algorithms. Results: The results show a significant correlation between Gleason pattern and the nuclear expression of the MSH2 protein and the cytoplasmic expression of the MLH1 protein. Gleason score significantly correlates with the nuclear and the cytoplasmic expression of the MSH2 protein and the cytoplasmic expression of the MDC1 protein. There is no correlation between the nuclear or cytoplasmic expression of the TP53BP1 protein and Gleason pattern or score. Conclusions: Our study suggests that the aberration in the MMR repair mechanism may be significantly more important regarding the grading among PC cells in comparison to the impact of alterations in the DSB repair mechanism. The lack of correlation between expression of the TP53BP1 protein and Gleason pattern and Gleason score suggests that the radiation resistance of PC is independent of alterations connected with TP53BP1.
