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
backgroundMultiple primary lung cancer (MPLC) represents a rare variety of pulmonary malignant tumor while mainly consist of double primary lung cancer (DPLC), but the development of diagnostic techniques promotes the rate diagnosis of it in recent years. Here we summarize and anylasis the data of 30 cases with DPLC in expectation of improving congnitive of MPLC.
methodsWe retrospectly studied 30 MPLC patients who diagnosed from January 2010 to December 2015 in Affiliated Cancer Hospital of Zhengzhou University. The clinical characteristics, diagnosis, therapeutic methods and prognosis were analyzed.
resultsAmong 30 patients enrolled, metachronous DPLC (27/30, 90%) is far more common than synchronous DPLC. The majority of the lesions located at right upper lobe (20/60, 33.3%), and adenocarcinoma (25/60, 41.7%) turns out to be the major pathological patter. Patients with same pathological pattern of two lesions of DPLC (17/30, 56.7%) were slightly more than those with different pattern (13/30, 43.3%) and adeno-adeno was the most common pattern in the former ones. Cox regression anylasis shows that lymphatic metastasis (HR=4.349, 95%CI: 1.435-13.178, P=0.009) and experience of heavy smoking (HR=2.996, 95%CI: 1.089-8.240, P=0.034) were associate with worse prognosis.
conclusionsDPLC are mainly located at right upper lobe, and mostly adenocarcinomas. Earlier diagnosis, active therapeutic approaches and a strict smoking cessation strategy may improve the prognosis of MPLC.
