Base deficit in the prognosis prediction of in-/out-of-hospital cardiac arrest patients.
Article in Internal and emergency medicine, 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
In cardiac arrest (CA) patients, arterial blood gas parameters, such as pH values, lactate concentrations, and base deficit (BD), are routinely evaluated in the emergency department (ED). We examined the relationship between BD and successful cardiopulmonary resuscitation (CPR), return of spontaneous circulation (ROSC), neurological surveys, and intensive care unit (ICU) hospitalization length for in-and out-of-hospital CA (IHCA and OHCA, respectively) patients. We included non-traumatic adult CA patients in the present study. Age, gender, arterial blood gas (ABG) test results, CPR duration, ROSC, ICU hospitalization length, 30-day surveys, and neurological surveys were obtained for each patient. We included 448 CA patients. The mean age of the study group was 62.80 ± 17.64 years. The number of OHCA patients was 251 (56%), and IHCA patients consisted of 197 (44%). Mean BD values of the non-surviving OHCA patients was - 16.67 ± 6.72. This corresponding value in survival patients value was - 14.89 ± 6.62, but the difference was not statistically significant (p = 0.420). In the IHCA group, a weak negative correlation between BD levels and CPR duration (p < 0.001, r = - 0.247) was found. A weak positive correlation between BD and ICU hospitalization length (p < 0.001, r = 0.342) was also found. CPR duration correlated weakly and negatively with BD in the OHCA group (p = 0.03, r = - 0.192). In the IHCA group, BD was related to both ROSC (p < 0.001) and 30-day survival (p < 0.001). In the OHCA group, BD was related to ROSC (p = 0.020) and 30-day surveys (p = 0.042). In the IHCA group, a weak negative correlation between BD levels and CPR duration in addition to a weak positive correlation between BD and ICU hospitalization length was found. CPR duration negatively correlated with BD in the OHCA group.
