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 the third most frequent cancer worldwide. It is the second leading cause of cancer-related death, affecting both men and women. It has been described that 20-25% of colorectal tumors have mutations in the PIK3CA gene, mainly in three hotspots: E542 and E545 and H1047. The aim of this study was to compare the prevalence of PIK3CA gene mutations in colorectal tumors based on a systematic review of a selection of studies. Nighty seven studies enrolling 48,446 patients were eligible for inclusion. Most studies were conducted in Asian (41.2%) and European countries (34.0%). The global prevalence ranged from 0 to 80%, with a mean prevalence of 13.7%. Fourteen studies reported a prevalence of less than 5%, 22 between 5 and 10%, 32 between 10 and 15% and 29 showed a prevalence of more than 15%. Mutations were more common in exon 9 than in exon 20 (9.5% vs. 4.7%). After discussing a number of possible reasons that could explain the differences in prevalence, it is very hard to deduce which is the main factor influencing the observed frequency.
