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

backgroundThe objective of the study was to examine the role of microsatellite instability (MSI) and BRAF(V600E)mutation in colorectal cancer (CRC) by categorising patients into more detailed subtypes based on tumour characteristics.

methodsTumour samples from 762 population-based patients with sporadic CRC were analysed for MSI and BRAF(V600E) by immunohistochemistry. Patient survival was followed-up for a median of 5.2 years.

resultsCompared with microsatellite stable (MSS) CRC, MSI was prognostic for better disease-free survival (DFS; 5 years: 85.8% vs 75.3%, 10 years: 85.8% vs 72.9%, P=0.027; HR 0.49, CI 0.30-0.80, P=0.005) and disease-specific survival (DSS; 5 years: 83.2% vs 70.5%; 10 years: 83.2 vs 65.0%, P=0.004). Compared with BRAF wild type, BRAF(V600E) was a risk for poor survival (overall survival; 5 years: 62.3% vs 51.6%, P=0.014; HR 1.43, CI 1.07-1.90, P=0.009), especially in rectal cancer (for DSS, HR: 10.60, CI: 3.04-36.92, P<0.001). The MSS/BRAF(V600E) subtype was a risk for poor DSS (HR: 1.88, CI: 1.06-3.31, P=0.030), but MSI/BRAF(V600E) was a prognostic factor for DFS (HR: 0.42, CI: 0.18-0.96, P=0.039). Among stage I-II patients, the MSS/BRAF(V600E) subtype was independently associated with poor DSS (HR: 5.32, CI: 1.74-16.31, P=0.003).

conclusionsMicrosatellite instable tumours were associated with better prognosis compared with MSS. BRAF(V600E) was associated with poor prognosis unless it occurred together with MSI. The MSI/BRAF(V600E) subtype was a favourable prognostic factor compared with the MSS/BRAF wild-type subtype. BRAF(V600E) rectal tumours showed particularly poor prognosis. The MSS/BRAF(V600E) subtype was associated with increased disease-specific mortality even in stage I-II CRC.
