Association Between Anemia and In-Hospital Outcomes in Patients With ST-Segment Elevation Myocardial Infarction at King Abdullah Medical City.

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
objectiveThis study aimed to assess the association between hemoglobin levels and in-hospital outcomes in patients with ST-segment elevation myocardial infarction (STEMI) at King Abdullah Medical City (KAMC).
methodsThis was a retrospective cohort study of 1,027 consecutive STEMI patients, from July 2022 to March 2023. The cohort was divided into two groups according to the presence of anemia on admission. Anemia was defined as hemoglobin levels of 12 g/dL in women and 13 g/dL in men: group 1 with anemia (255 (24.8%)) and group 2 without anemia (772 (75.2%)). Multiple logistic regression was used to examine the factors affecting in-hospital complications.
resultsTwo hundred fifty-five (24.8%) patients were anemic at admission. Anemia was higher in women than men (49.7% vs. 20.5%; p < 0.001). The anemic group was older (59.5 ± 12.97 vs. 53.3 ± 11.76 years; p < 0.001) and had a higher prevalence of hypertension and diabetes mellitus (DM) (63.5% vs. 44.6% (p < 0.001) and 65.9% vs. 55.7% (p = 0.005), respectively). The anemic group had longer hospital stays (6.5 ± 7.4 vs. 4.77 ± 4.9 days; p < 0.001) and a higher in-hospital death rate (5.9% vs. 2.5%; p = 0.014). Using multivariate analysis, anemia was not a significant independent predictor for in-hospital complications.
conclusionAnemia is a common comorbidity in STEMI patients. It is associated with a 2.5-fold increase in in-hospital mortality and a significantly longer length of hospitalization.
