Meta-analysis of mortality-associated factors in primary Sjögren’s syndrome patients with interstitial lung disease
Bibliographic record
Abstract
Abstract The study aims to conduct a meta-analysis on 5-year survival rate and mortality-related factors in the patients with primary Sjögren’s syndrome concomitant with interstitial lung disease (pSS-ILD). Following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched various platforms and databases until November 22, 2023. We used the Newcastle–Ottawa Scale (NOS) for quality assessment and extracted study characteristics and effect sizes. The pooled 5-year survival rate, hazard ratios (HRs), and the corresponding 95% confidence intervals (95% CIs) were then calculated. A p-value of less than 0.05 was considered statistically significant. Patients with pSS-ILD. Mortality in patients with pSS-ILD. Out of 188 articles, seven met the inclusion criteria. The meta-analysis estimated a 5-year survival rate of 82% (73%-91%). Mortality-related factors estimated by the meta-analysis included older age (HRs = 1.06, 95% CI 1.03–1.09, P < 0.0001), history of smoking (HRs = 3.44, 95% CI 2.14–5.53, P < 0.00001), anti-SSA antibody positivity (HRs = 0.41, 95% CI 0.20–0.85, P = 0.02), anti-SSB antibody positivity (HRs = 0.42, 95% CI 0.18–0.98, P = 0.04), reduced forced vital capacity (FVC; HRs = 0.96, 95% CI 0.95–0.98, P < 0.0001), reduced 6-min walk distance (6MWD; HRs = 0.99, 95% CI 0.99–1.00, P = 0.0008), presence of a reticular abnormality (HRs = 3.03, 95% CI 1.54–5.95, P = 0.001), and decreased arterial partial pressure of oxygen (PaO 2 ) levels (HRs = 0.99, 95% CI 0.97–1.00, P = 0.04). The 5-year survival rate for pSS-ILD is 82%. Older age, history of smoking, anti-SSA antibody negativity, anti-SSB antibody negativity, reduced FVC, reduced 6MWD, presence of a reticular abnormality, and decreased PaO 2 levels increase the mortality risk in pSS-ILD.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
