1 · What the graph read from it

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.

2 · The registry

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

Objective: To investigate the impact of long-term passive smoking on the pathogenesis of chronic obstructive pulmonary disease (COPD) in women. Methods: We conducted a community-based cross-sectional study involving 2,360 women aged ≥40 years in Jinan, China (October 1, 2022-April 30, 2023). Participants underwent comprehensive assessments including pulmonary function tests (spirometry), hematological analyses, and structured questionnaires evaluating COPD symptoms and passive smoking exposure. Based on exposure history, subjects were stratified into long-term passive smoking (LPS, n = 610) and non-passive smoking (NPS, n = 1,750) cohorts. Results: Comparative analysis revealed significant pulmonary function impairment in the LPS group versus NPS controls: lower FEV1 (2.97±0.61 vs 3.25±0.37 L, p < 0.05), reduced FEV1% predicted (78.20±10.18 vs 81.47±14.69, p < 0.05), decreased FEV1/FVC ratio (83.32±11.20 vs 87.23±10.32%, p < 0.05). Small airway dysfunction was more pronounced in LPS participants, evidenced by: diminished MEF75% (77.58±11.95 vs 86.08±14.02 L/s, p < 0.05), reduced MEF50% (62.76±19.79 vs 89.36±16.78 L/s, p < 0.05), lower MMEF (80.87±12.80 vs 87.46±11.26 L/s, p < 0.05). The LPS group demonstrated: higher prevalence of preserved ratio impaired spirometry (PRISm, 5.74% vs 2.91%); increased annual exacerbation frequency (p < 0.05), elevated systemic inflammatory markers (p < 0.05), greater symptom severity (p < 0.05). Conclusion: Our findings demonstrate that chronic passive smoke exposure constitutes an independent risk factor for COPD development in women, associated with higher disease prevalence, accelerated pulmonary function decline, increased exacerbation frequency and enhanced systemic inflammation.
