Complications of silicone airway stents in malignant and benign central airway stenosis: timing of complications and survival outcomes.
Article in Annals of Saudi medicine. 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
backgroundSilicone airway stents restore airway patency in central airway stenosis but may be complicated by migration, mucostasis, granulation tissue, and tumor overgrowth.
objectiveTo compare complication profiles, timing of complications, and survival outcomes after silicone airway stent placement in malignant versus benign central airway stenosis.
designRetrospective comparative cohort study.
settingSingle center, tertiary referral interventional bronchoscopy unit in Ankara, Türkiye. PATIENTS AND
methodsConsecutive adults who underwent silicone airway stent placement by rigid bronchoscopy between September 2012 and July 2017 were reviewed and analyzed.
main outcome measuresComplication distribution by etiology, time to first complication, complication-free survival, and stent survival. SAMPLE SIZE: 80 patients (59 malignant, 21 benign).
resultsComplications occurred in 48% of benign and 30% of malignant cases, with significant differences in complication profiles between groups (
conclusionsSilicone airway stenting is associated with distinct complication patterns and timing in benign and malignant central airway stenosis. These findings support structured post-stent bronchoscopic surveillance. LIMITATIONS: Retrospective single-center design, small benign subgroup, symptom-driven follow-up, and potential confounding and immortal-time bias in survival analyses.
