1 · What the graph read from it

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.

2 · The registry

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

Purpose: Globally, colorectal cancer (CRC) stands as the third most common type of cancer, a ranking that has remained consistent over recent years. However, the scenario diverges in Saudi Arabia, where CRC ascends to the forefront as the most common cancer among males and the second most prevalent among females. This discrepancy is primarily driven by male demographics, with a staggering 73% of cases diagnosed at a late stage, underscoring a critical public health concern. Delving into the molecular and phenotypic profiles of CRC within the Saudi populace emerges as a crucial stride towards addressing the escalating disease burden afflicting the country. Methods: To unravel the CRC driver molecular landscapes among the Saudi population, we performed Whole Exome Sequencing (WES) of 50 Saudi CRC patients collected by the Colorectal Cancer Research Center at King Saud University Medical Center (KSUMC) with MSS adenocarcinoma tumors. These patients were compared with comparable tumor cohorts from MD Anderson Cancer Center (MDACC) and The Cancer Genome Atlas (TCGA). Results: Tumors from Saudi patients have a significantly lower frequency of Conclusion: The results indicate a distinct mutational landscape of CRC in Saudi Arabia, highlighting the importance of gathering population-specific data in order to inform diagnostic of molecular cancer screening and treatment strategies for patients in Saudi Arabia.
