Clinical characteristics of lung cancer in patients with connective tissue disease associated interstitial lung disease: a brief report.
Article in Clinical rheumatology, 2026. 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
INTRODUCTION/
objectivePatients with connective tissue disease-associated interstitial lung disease (CTD-ILD) have an increased risk of developing lung cancer (LC).This study investigated whether non-receipt of immunosuppressive therapy is associated with LC risk in CTD-ILD patients and identified associated risk factors.
methodsThis retrospective study reviewed 262 patients with CTD-ILD. Patients were divided into an LC group (n = 29) and non-LC group (n = 233). Logistic regression identified risk factors for LC.
resultsNon-receipt of corticosteroids and/or immunosuppressants (OR 6.675; 95%CI 2.000-22.272; P = 0.002) and usual interstitial pneumonia (UIP) pattern (OR 2.845; 95% CI 1.077-7.519; P = 0.035) were independent risk factors for LC. Most LC patients were stage IV (58.6%). Patients with LC had significantly poorer survival than those without (median 22.3 vs. 168.9 months; HR 11.392; 95% CI 6.163-21.057; p < 0.001).
conclusionsNon-receipt of immunosuppressive therapy and UIP pattern are independently associated with LC risk in CTD-ILD. The poor prognosis and advanced stage at diagnosis emphasize the need for early LC detection. Key Points • The UIP pattern and non-receipt of immunosuppressive therapy were independently associated with LC risk, although these findings are not causal.
