Pretreatment elevated serum lactate dehydrogenase as a significant prognostic factor in malignant mesothelioma: A meta-analysis.
Synthesis in Medicine, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled 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.
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
backgroundLactate dehydrogenase (LDH) as a hypoxia-regulator plays a vital role in alternative metabolic pathways of cancer cells. Numerous studies have assessed the prognostic value of elevated pretreatment LDH in malignant mesothelioma (MM). However, the results have been largely inconsistent. Hence, the aim of current study was to investigate the prognostic value of pretreatment LDH levels in patients with MM by performing a meta-analysis of relevant studies.
methodsA literature search for English language studies, which investigated the association of LDH levels with overall survival (OS) in malignant mesothelioma, was performed in the electronic databases, PubMed, Medline, Embase, and Web of Science. Pooled hazard ratios (HRs) and their 95% confidence intervals (95% CIs) were calculated. Heterogeneity was assessed using Cochran Q and I statistics. Sensitivity analysis, meta-regression model, and subgroup analysis were performed to trace the source of heterogeneity, if applicable.
resultsA total of 9 studies with a combined study population of 1977 patients came within the purview of this meta analysis. Pooled HR for OS in patients with high LDH level was 1.68 (95% CI = 1.36-2.00). Significant heterogeneity was observed in the included studies (I = 54.1%, P = 0.026). Sensitivity analysis after sequential exclusion of 1 study at a time, and meta-regression with inclusion of 6 confounding factors failed to identify the source of heterogeneity. However, in the subgroup analysis, it was found that the publication of Nojiri et al was the origin of heterogeneity. When omitted the publication of Nojiri et al, the pooled HR of the rest 8 studies was 1.83 (95% CI = 1.45-2.20, I = 0.0%, P = 0.723). Egger test and funnel plots excluded the possibility of publication bias affecting the results of the current meta-analysis.
conclusionA negative association was observed between high LDH levels and poor overall survival in the current study. Our findings suggest that pretreatment LDH level could serve as a useful predictor of prognosis in patients with malignant mesothelioma.
