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

backgroundDiabetes mellitus (DM) is one of the most common comorbidities in surgically treated non-small cell lung cancer (NSCLC) patients and has a negative impact on short-term outcomes. However, the impact of DM on long-term survival of such patients remains controversial; therefore, we conducted a comprehensive updated meta-analysis.

methodsWe systematically searched relevant studies in PubMed, Embase, Cochrane Library, and Web of Science up to 6 September 2018. Hazard ratios (HRs) for the impact of DM on overall survival (OS) and recurrence-free survival (RFS) of patients with surgically treated NSCLC were extracted and analyzed using the STATA 12.0 package.

resultsWe included 13 cohort studies consisting of 4343 patients (730 patients with DM and 3613 patients without) with surgically treated NSCLC. Meta-analysis showed that patients with DM had significantly poorer OS (random effects: HR 1.30, 95% confidence interval 1.05-1.60; P = 0.016) than those without. However, with a limited sample size, there was no significant difference in RFS (random effects: HR 1.06, 95% confidence interval 0.71-1.58; P = 0.786) between patients with and without DM after surgical resection of NSCLC.

conclusionDM is an independent unfavorable prognostic factor for patients with surgically treated NSCLC. High-quality studies with appropriate adjustment for confounding factors are needed to confirm our conclusions.
