Preoperative Master's double two-step test may predict survival after lobectomy in patients with lung cancer.

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
backgroundThe Master's double two-step test (MDT), which is used to screen for coronary heart disease, is difficult for physically impaired patients to complete. The purpose of this study was to clarify the relationship between the results of the MDT and prognosis after lung cancer surgery.
methodsBetween May 2004 and September 2019, 1,434 patients underwent complete resection for lung cancer at our hospital. Among them, 418 with pathological stage I disease who underwent lobectomy were evaluated. We defined patients who could accomplish the MDT as the complete MDT group and those who could not as the incomplete MDT group. Patients who could not perform the MDT due to physical problems were included in the incomplete MDT group. We explored the prognostic impact of the MDT results in these patients.
resultsFifty-three patients (12.7%) were in the incomplete MDT group; compared with the complete MDT group, they were older and had poorer performance status and respiratory function. However, the incidence of postoperative complications and 90-day mortality did not differ significantly between groups. Multivariate analyses revealed that age (p < 0.001), Charlson comorbidity index (p = 0.013), incomplete MDT (p = 0.049) and carcinoembryonic antigen (CEA) level (p = 0.003) were prognostic factors for worse overall survival; age (p < 0.001) and incomplete MDT (p = 0.022) were prognostic factors for worse non-cancer-specific survival.
conclusionsAlthough incomplete MDT was not associated with postoperative complications, 90-day mortality or cancer-specific survival, MDT results may be significantly associated with non-cancer-specific survival.
