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

backgroundBevacizumab, a humanized monoclonal antibody against vascular epithelial growth factor, plays a significant role in first-line, second-line, beyond-progression, and maintenance treatment of patients with metastatic colorectal carcinoma (mCRC). Nevertheless, there are currently no biomarkers available to predict patient response or resistance to bevacizumab, which would be useful in clinical trials.

methodsUsing PRISMA guidelines, we conducted a systematic review and meta-analysis of the association between serum lactate dehydrogenase (LDH) level and progression-free survival (PFS), overall survival (OS), and objective response rate in mCRC patients treated with bevacizumab-based first-line chemotherapy. A comprehensive, computerized literature search of PubMed, the Web of Science, Scopus, Ovid, and the gray literature was performed. Only studies conforming to specific eligibility criteria were included. Pooled hazard ratios (HRs) were estimated using random-effects or fixed-effects models according to heterogeneity between studies. Sensitivity analysis was conducted to evaluate the stability of the results by removing each individual study from the meta-analysis.

resultsSeven eligible studies of 1,219 total patients were included in the analysis. Meta-analysis of all studies revealed that high serum LDH level is associated with shorter PFS (HR: 1.43, 95% CI: 1.05-1.94; P=0.023) and OS (HR: 1.667, 95% CI: 1.230-2.259; P=0.001) times in mCRC patients treated with bevacizumab-based first-line chemotherapy. However, there was no significant association between serum LDH and objective response rate.

conclusionsHigh serum LDH level is significantly associated with shorter PFS and OS time and may have utility as a prognostic factor for mCRC patients receiving bevacizumab as first-line chemotherapy and as a predictive factor for those receiving bevacizumab-based therapy at other times.
