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

purposeThe sequential organ failure assessment (SOFA) score was recently updated to better reflect contemporary intensive care. This study compares the predictive validity of the updated SOFA-2 and the previous SOFA-1 for 30-day mortality over the first week in ICU, overall and in subgroups with distinct age and comorbidity profiles.

methodsWe conducted a retrospective observational study of adult patients admitted to four ICUs in Sweden from 2010 to 2021. Predictive validity for 30-day mortality was assessed on day 1-7 using the area under the receiver operating characteristic curve (AUROC).

resultsWe included 29,820 admissions (mean age 60 years, 64.8% males, median Charlson comorbidity index [CCI] 1). Reclassification between SOFA-1 and SOFA-2 occurred in 75-79% of admissions across days 1-7. On day 1, the AUROC for 30-day mortality was 0.81 (95% CI 0.80-0.81) for SOFA-2 and 0.80 (95% CI 0.79-0.81) for SOFA-1 (p < 0.001). From day 2 onward, AUROCs declined for both scores and were largely similar. Among trauma patients (mean age 50 years; median CCI 0), day-1 AUROC for SOFA-2 was 0.81 (95% CI 0.79-0.83), while among sepsis patients (mean age 61 years; median CCI 3) it was 0.72 (95% CI 0.70-0.74), with comparable performance for SOFA-1.

conclusionsSOFA-2 provided modestly better discrimination for 30-day mortality on ICU-day 1 compared with SOFA-1. Predictive validity diminished over subsequent days for both scores and varied across subgroups with different age and comorbidity distributions, underscoring the context-dependence of organ dysfunction scoring.
