Association between hydrocortisone use and outcomes in sepsis patients with hospital-acquired bloodstream infections: An ancillary analysis of the EUROBACT-2 cohort.
Article in PloS one, 2026. 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
purposeCorticosteroids are suggested for selected patients with septic shock, but their association with outcomes has not been specifically investigated in patients with hospital-acquired bloodstream infections (HA-BSI). We explored the association between hydrocortisone use and day-28 mortality in this population.
methodsData from the prospective EUROBACT-2 study were used to assess the association between hydrocortisone use and day-28 mortality in ICU patients with HA-BSI and sepsis. Patients receiving hydrocortisone were compared with patients not receiving hydrocortisone. A 1:1 propensity score matching procedure was performed using nearest-neighbour matching without replacement and a caliper of 0.2 standard deviation of the logit propensity score, followed by multivariable logistic regression with cluster-robust standard errors by matched pair.
resultsAmong 2,401 analyzed patients, 608 (25%) received hydrocortisone during the HA-BSI episode. The final propensity score included age, sex, Charlson comorbidity score, ICU admission diagnosis, SOFA score without cardiovascular component, septic shock, country of inclusion, lactate at HA-BSI diagnosis, and ICU-acquired versus non-ICU-acquired HA-BSI. Matching yielded 521 pairs (1,042 patients). In the multivariable model, hydrocortisone use was associated with increased day-28 mortality in the overall matched cohort (OR 1.448; 95% CI 1.096-1.914; p = 0.009). This association was observed in patients with sepsis without shock (OR 1.697; 95% CI 1.051-2.740; p = 0.031) and in the female subgroup (OR 1.718; 95% CI 1.055-2.796; p = 0.030), but not in patients with septic shock or in those receiving norepinephrine-equivalent dose ≥0.25 µg/kg/min.
conclusionHydrocortisone use was not associated with improved day-28 survival in ICU patients with HA-BSI. In the matched analysis, hydrocortisone use was associated with higher day-28 mortality in the overall cohort, whereas no significant association was observed in patients with septic shock or high-dose norepinephrine. These findings are observational and hypothesis-generating and should not be interpreted causally.
