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

backgroundLung cancer is the first cause of cancer mortality worldwide. Chronic obstructive pulmonary disease (COPD) is an independent risk factor for lung cancer. An epidemiological survey discovered that the presence of COPD increases the risk of lung cancer by 4.5-fold. Lobectomy is considered to be the standard surgical method for early stage non-small cell lung cancer (NSCLC). However, the influence of lobectomy on the loss of pulmonary function has not been fully investigated in NSCLC patients with COPD.

methodsWe searched the PubMed database using the following strategies: COPD and pulmonary function test (MeSH term) and lobectomy (MeSH term) from 01 January 1990 to 01 January 2019. We selected the articles of patients with COPD. A total of six studies, including 195 patients with COPD, provided lung function values before and after surgery.

resultsFive out of six studies focused on the short-term change of pulmonary function (within 3-6 months) after lobectomy, and the average loss of FEV1 was 0.11 L (range: -0.33-0.09 L). One study investigated the long-term change of pulmonary function (within 1-2 years) after lobectomy, and the average loss of FEV1 was 0.15 L (range: -0.29-0.05 L).

conclusionsA short-term (3-6 months) loss of pulmonary function after operation is acceptable for lung cancer patients with COPD. However, there may be a high risk of postoperative complications in NSCLC patients with COPD. Therefore, surgical treatment needs to be carefully considered for these patients.
