The prognostic analysis of lung cancer patients with occult malignant pleural disease at thoracotomy.
Article in Translational cancer research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis study aims to determine the clinicopathological prognostic factors for occult malignant pleural disease (MPD) that were first detected in patients with non-small cell lung cancer (NSCLC) at thoracotomy and to assess the outcome of surgical intervention.
methodsA total of 120 thoracotomy-patients with MPD were examined. The Kaplan-Meier test estimated survival curves, and Cox regression analysis was performed to validate the risk factors picked. In assessing surgical intervention, clinical and pathological parameters were matched by propensity score matching (PSM).
resultsWith a median follow-up of 34 months, the 5-year overall survival of 120 patients was 28.0%. Multivariate analyses showed male (P=0.044), advanced T stages (P<0.001), advanced N stages (P=0.02), pleural invasion in image (P=0.005), pleural effusion (P=0.027), surgical intervention (P=0.008) and EGFR status (P=0.003) were independent predictors of survival. The 5-year survival rate and median survival time (MST) for 21 patients with lobectomy and pleurectomy were 71.6% and undefined, compared with 25.6% and 40.0 months in 46 patients with sublobectomy. When 53 patients only subjected to open-close surgery, their 5-year survival rate and MST were 23.4% and 30.2 months. After PSM, both 21 patients were included in lobectomy with the pleurectomy group and sublobectomy /open-close group. The overall survival of lobectomy with the pleurectomy group was better than the control group (P=0.046).
conclusionsAge, stage, pleural invasion, pleural effusion, surgical intervention, and EGFR status affected the prognosis of the MPD patients first diagnosed at thoracotomy. Selective surgery gives better recovery, and additional studies are needed.
