Pre-Hospital Calcium Administration Reduces Incidence of Hypocalcemia and Mortality in Trauma Patients.
Article in Open access emergency medicine : OAEM, 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
Background: Extensive literature has established how critical calcium is to countless physiological pathways; however, the consequences of trauma-induced hypocalcemia, if not pro-actively managed, are often overlooked. Data suggests that timely calcium administration may be advantageous in correcting hypocalcemia and preventing unfavorable clinical outcomes. There is limited data examining the impact of pre-hospital calcium administration in trauma patients transported from the injury scene by air ambulance. Our Lifeline air transport service initiated a pre-hospital calcium administration protocol in October 2021. Objective: To determine the efficacy of the pre-hospital calcium protocol on ED ionized calcium (iCa) values and clinical outcomes. Methods: A single-center, retrospective cohort analysis of 87 trauma patients transported from the scene via Lifeline air services was conducted. Cohort 0 had 54 patients who received pre-hospital blood products without calcium, and Cohort 1 had 33 patients who received blood products and calcium. Eleven patients were excluded from final analysis due to missing iCa values. Results: Cohort 1 had significantly higher iCa values (4.92 ± 0.74 vs 4.24 ± 0.76 mg/dL, Conclusion: The administration of pre-hospital calcium significantly reduced episodes of hypocalcemia and severe hypocalcemia.
