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
introductionThe purpose of this study was to examine the prevalence, clinical characteristics, and changing trends of non-smokers with lung cancer (LC) based on data from a population-wide cancer registry in northern China.
methodsThe study used LC incidence and follow-up data from 2010 to 2019 from the Cancer Registry System of Tianjin city, which included 82769 cases. Trends in the incidence and proportion of non-smokers with LC were examined by joinpoint regression analysis. Life table and Cox survival analyses were used to calculate the survival rates and compare the death hazard ratios (HRs) in different groups, respectively.
resultsAmong the 82769 new diagnosis cases of LC during 2010 to 2019, there were 34589 (41.8%) current smokers, 14913 (18.0%) ex-smokers, 28123 (34.0%) non-smokers, and 5144 (6.2%) unknowns. The proportion of non-smokers changed slightly from 2010 (35.36%) to 2019 (36.87%) (annual percentage change, APC= -0.01%, p>0.05). This proportion declined in men (2010 vs 2019; 22.06% vs 20.66%) and increased in women (2010 vs 2019; 53.02% vs 62.35%), and in the 0-44 years age group it showed an upward trend from 2015 to 2019 (APC=4.82%, 95% CI: 1.8-7.9). Compared with smokers with LC, non-smokers with LC were predominantly females (64.15% vs 27.26%), had a predominantly adenocarcinoma histological subtypes (76.71% vs 42.22%), and had a 20% lower risk of death than smokers (HR=0.80; 95% CI: 0.78-0.81).
conclusionsThe proportion of non-smokers with LC was relatively high in northern China, with an increasing trend in the proportion of females and younger age groups. Non-smokers with LC had different epidemiological and clinical characteristics compared with smokers with LC.
