Yield and safety of different biopsy types in interstitial lung disease: a systematic review and meta-analysis.
Synthesis in European respiratory review : an official journal of the European Respiratory Society, 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
backgroundLung biopsy remains an important consideration in the management of interstitial lung disease (ILD). Transbronchial lung cryobiopsy (TBLC) offers an alternative to traditional surgical lung biopsy (SLB) and transbronchial forceps biopsy (TBB); however, up-to-date comparisons between these methods in ILD, particularly fibrotic ILD, remain limited.
methodsA comprehensive literature search of Medline, Embase and Evidence-Based Medicine Reviews was performed for studies published between January 2000 and September 2025 to identify all citations reporting yield and complications of the three main lung biopsy methods for ILD.
resultsA total of 143 studies were included. Pooled multidisciplinary yield (following multidisciplinary discussion) in TBB, TBLC and SLB was 35.3% (95% CI 21.3-52.5), 84.3% (95% CI 81.7-86.5) and 88.6% (95% CI 83.4-92.3), respectively. For fibrotic ILD, the multidisciplinary yield was 12.5% (only one eligible study), 87.6% (95% CI 83.5-90.7) and 87.3% (95%CI 80.5-92.0), respectively. Meta-regression showed an increasing multidisciplinary yield of TBLC with more recent years of patient recruitment and an increasing percentage of fibrotic ILD in each study. The multidisciplinary yield of both TBLC and SLB was 85-90%, suggesting a biopsy "ceiling effect". All evaluated complications were more frequent in TBLC compared to TBB and some were more frequent in SLB compared to TBLC. Several complications were more frequent in fibrotic ILD compared to all ILD.
conclusionsThe multidisciplinary yield of TBLC and SLB is equivalent, with both offering an acceptable safety profile. TBB has low yield, particularly in fibrotic ILD. These findings support using either TBLC or SLB as an initial diagnostic tool in fibrotic ILD, mainly based on patient-physician shared decision-making.
