Primary clear cell adenocarcinoma of the lung: a national analysis.
Article in Journal of thoracic disease, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background: Primary clear cell adenocarcinoma of the lung (CCAL) is a rare form of lung cancer with poorly understood clinical features. We sought to investigate the clinicopathological characteristics and independent prognostic factors of primary CCAL. Methods: Overall survival (OS) of patients with CCAL in the National Cancer Database (NCDB) from 2004 to 2017 was compared to lung adenocarcinoma using Kaplan-Meier analysis, multivariable Cox proportional hazards modeling, and propensity score matching. Independent prognostic indicators for patients with CCAL were determined using multivariable Cox proportional hazards analysis. Results: A total of 1,396 CCAL and 462,360 lung adenocarcinoma patients were included in our analysis. When compared to patients diagnosed with lung adenocarcinoma, those diagnosed with CCAL were more likely to be younger, white, reside farther from a hospital, have higher Charlson/Deyo comorbidity condition (CDCC) scores, have private insurance, have T1, N0, M0 status. In unadjusted analysis, patients with CCAL had better survival than those with lung adenocarcinoma, although no significant differences in survival were found between the two groups with multivariable Cox proportional hazards and propensity score-matched analyses. Conclusions: In this national analysis, we found that the clinicopathological characteristics of CCAL are distinct from those of lung adenocarcinoma, but CCAL is not itself an independent predictor of survival after multivariable adjustment or propensity score-matched analysis.
