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

Epidemiologic studies have evaluated the association between BRAF mutations and resistance to the treatment of anti-EGFR monoclonal antibodies (MoAb) in patients with metastatic colorectal cancer (mCRC). However, the results are still inconclusive. To derive a more precise estimation of the relationship, we performed this meta-analysis. A total of 11 studies were included in the final meta-analysis. There were seven studies for unselected mCRC patients and four studies for patients with wild type KRAS mCRC. Among unselected mCRC patients, BRAF V600E mutation was detected in 48 of 546 primary tumors (8.8%). The objective response rate (ORR) of patients with mutant BRAF was 29.2% (14/48), whereas the ORR of patients with wild-type BRAF was 33.5% (158/472).The overall RR for ORR of mutant BRAF patients over wild-type BRAF patients was 0.86 (95% CI=0.57-1.30; P=0.48). For patients with KRAS wild-type mCRC, BRAF V600E mutation was detected in 40 of 376 primary tumors (10.6%). The ORR of patients with mutant BRAF was 0.0% (0/40), whereas the ORR of patients with wild-type BRAF was 36.3% (122/336). The pooled RR of mutant BRAF patients over wild-type BRAF patients was 0.14 (95% CI=0.04-0.53; P=0.004). In conclusion, this meta-analysis provides evidence that BRAF V600E mutation is associated with lack of response in wild-type KRAS mCRC treated with anti-EGFR MoAbs. BRAF mutation may be used as an additional biomarker for the selection of mCRC patients who might benefit from anti-EGFR MoAbs therapy.
