Virtual multidisciplinary discussion across borders for interstitial lung disease: a prospective, multicentre study from India, the UK, Greece and Sri Lanka.
Article in BMJ open, 2025. 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
objectivesTo assess diagnostic concordance and reclassification following an India-led, multinational virtual multidisciplinary discussion (V-MDD) platform for interstitial lung disease (ILD).
designProspective, multicentre service-evaluation study.
settingTwenty-four Indian referral centres connected through a secure virtual platform, with international faculty participation from the UK, Greece and Sri Lanka.
participantsA total of 127 anonymised ILD cases discussed across 29 V-MDD sessions (February 2024-February 2025). Each panel included ≥4 pulmonologists, two pulmonary pathologists, one of three rotating thoracic radiologists and one of two rheumatologists, along with international experts.
resultsThe cohort (mean age 52.6±16.1 years; 53.5% female (68/127)) most frequently presented with dyspnoea (82.6%) and cough (73.2%). Pre-V-MDD diagnoses included hypersensitivity pneumonitis (HP) and sarcoidosis as distinct disease entities, and usual interstitial pneumonia (UIP) and non-specific interstitial pneumonia (NSIP) as radiological patterns, along with connective tissue disease (CTD)-ILD and other ILDs. Concordance between pre- and post-V-MDD CT diagnoses was substantial (κ=0.658; 95% CI 0.562 to 0.754; p <0.001). Histopathology concordance was similarly high (κ=0.861 for HP; κ=0.650 for other ILDs). Overall, 23% of cases were reclassified following discussion. Diagnostic stability was greatest for organising pneumonia, CTD-ILD and UIP pattern, whereas HP and sarcoidosis showed the highest reclassification rates.
conclusionsThe India-led, multinational V-MDD model demonstrated substantial diagnostic concordance and refined nearly one-quarter of ILD diagnoses. This virtual, scalable framework expands access to subspecialty expertise and offers a practical blueprint for standardising ILD care in resource-limited and cross-border settings.
