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

backgroundThis study aims to quantitatively summary the characteristics of synchronous multiple primary lung cancer (sMPLC), postoperative mortality, long-term prognosis, and prognostic effects of potential clinical parameters in patients with sMPLC after surgery.

methodsPubMed and Embase databases were systematically searched to identify studies that explored the prognosis of patients with sMPLC after surgery.

resultsFifty-two studies with 3486 participants were included, and clinical characteristics were quantitatively summarized. The pooled proportion of sMPLC in lung cancer was 2.0% (95%CI, 1.6%-2.5%) with an increasing trend over time, and postoperative mortality was 1.4% (95%CI, 0.5%-2.7%) with a decreasing trend over time. The 5-year survival rate was 44.9% (95%CI, 37.4%-52.6%) and all long-term survival rates showed increasing trends over time. Poor long-term prognosis was observed in both limited resection (HR = 1.357, 95%CI, 1.047-1.759, p = 0.0210) and pneumonectomy (HR = 2.643, 95%CI, 1.539-4.541, p = 0.0004) by comparison of anatomical resection. Other clinical parameters of age, gender, smoking status, FEV1, and lymph node metastasis significantly impacted the long-term prognosis (all p < 0.05).

conclusionsThe proportion of sMPLC in lung cancer and 5-year survival rate are increasing, while postoperative mortality is decreasing trend over time. Lobectomy should be preferred, while pneumonectomy should be avoided for sMPLC. Age, gender, FEV1, smoking, tumor size, surgical methods, and lymph node status are prognostic factors for sMPLC. Considering the heterogeneity and publication bias, these findings should be treated with caution.
