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

Colorectal cancer (CRC) is one of the most common cancers worldwide. Lynch Syndrome (LS) is the most common form of hereditary CRC and it is caused by germline defects in the DNA-mismatch repair (MMR) pathway. It is of extreme importance for affected LS patients and their relatives to identify the germline causative alteration to provide intensified surveillance to those at risk and allow early diagnosis and cancer prevention. Current approaches for LS molecular diagnosis typically involve screening of the MMR genes by targeted gene-panel sequencing and rearrangement screening. We report the identification and characterization of a novel germline structural variant encompassing 48.757 kb, involving the 3'-ends of the MLH1 and LRRFIP2 genes, as the cause of LS in a family of Ecuador. Whole-genome sequencing and transcriptomics allowed the identification of the genomic rearrangement and highlights the importance of the use of these additional approaches to achieve a comprehensive molecular diagnosis in some LS patients.
