Association between ventilatory ratio and mortality in acute respiratory distress syndrome: protocol for a systematic review and meta-analysis using a hierarchical Bayesian model.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionThe ventilatory ratio (VR) is a simple and accessible index that reflects ventilatory efficiency in critically ill patients. Although several studies have examined its potential as a prognostic marker in acute respiratory distress syndrome (ARDS), the results remain inconsistent and inconclusive. This systematic review and Bayesian meta-analysis aimed to evaluate the association between VR and mortality in adult patients with ARDS. METHODS AND ANALYSIS: Two investigators will independently conduct systematic literature searches in the PubMed, Embase, Scopus, Cochrane Library and Latin American and Caribbean Health Sciences Literature / Literatura Latinoamericana y del Caribe en Ciencias de la Salud (LILACS) databases, covering all publications from database inception to July 2025.This systematic review and meta-analysis will include prospective and retrospective cohort studies evaluating the association between the VR and mortality in adult patients with ARDS. Specifically, we aim to answer the following ETHICS AND DISSEMINATION: This systematic review does not require ethics approval. The results will be published in scientific journals, presented at national and international conferences and shared on social media in accessible language. PROSPERO REGISTRATION NUMBER: CRD420251008773.
