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

backgroundPatients who undergo tracheostomy and remain ventilator-dependent for over 21 days (defined as prolonged mechanical ventilation, PMV) represent a critically ill subgroup with high long-term mortality. Existing prognostic models such as the ProVent score may not fully capture the specific risk profile of these patients. This study aimed to develop and validate a novel prognostic model, the Tracheostomy-ProVent score, to predict 3-, 6-, and 12-month mortality using clinical variables measured on day 21 of mechanical ventilation.

methodsThis retrospective cohort study included 213 tracheostomized adult patients who received invasive mechanical ventilation for more than 21 consecutive days in a tertiary care hospital between February 2011 and February 2023. Multivariate logistic regression was used to identify predictors of mortality and construct a scoring model. Model performance was assessed using area under the receiver operating characteristic curve and calibration analyses.

resultsThe cumulative mortality rates in our patient cohort were 55.9%, 62.5%, and 66.7% at the 3-month, 6-month, and 1-year time points, respectively. The Tracheostomy-ProVent score showed strong predictive accuracy, with areas under the receiver operating characteristic curves of 0.871, 0.886, and 0.875 for 3-, 6-, and 12-month mortality, respectively. Notably, the new score significantly outperformed the original ProVent score in predicting 1-year mortality (AUC 0.875 vs. 0.768). The key clinical variables that were consistently associated with mortality included the requirement for vasopressors, platelet count of < 150 × 10³/µL, PaO₂/FiO₂ ratio of < 200 mmHg, and serum albumin level of ≤ 2.8 g/dL on day 21 of MV.

conclusionThe Tracheostomy-ProVent score demonstrates potential as a valuable tool for advanced risk stratification in tracheostomized patients. However, external validation is required to confirm its generalizability prior to widespread clinical application.
