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

BACKGROUND AND

objectiveThe white blood cell-to-haemoglobin ratio (WHR) is a comprehensive indicator of inflammation and anaemia status. However, the relationship between the WHR and the risk of 30-day mortality among intensive care unit (ICU) patients with pulmonary hypertension (PH) remains unclear. The purpose of this study was to investigate the association between the WHR and 30-day mortality in critically ill patients with PH.

methodsClinical data of patients with PH were extracted from the MIMIC-IV (2.2) database. Restricted cubic splines and logistic regression analysis were used to investigate the relationship between the WHR and 30-day mortality. Subgroup analysis was used to assess the robustness of the results.

resultsA total of 451 patients with PH were enrolled, with 78 (17.3%) dying within 30 days. Restricted cubic spline analysis revealed a linear relationship between the WHR and 30-day mortality. Logistic regression analysis revealed the WHR was an independent predictor for 30-day mortality in critically ill patients with PH (OR, 1.58; 95% CI, 1.05-2.37; P = 0.028). The AUC of the WHR was 0.646 (95% CI: 0.60-0.69).

conclusionsA higher WHR was an independent predictor for 30-day mortality in critically ill patients with PH. CLINICAL TRIAL NUMBER: Not applicable.
