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

introductionCardiac etiologies are one of the main causes for out of hospital cardiopulmonary arrest (OHCA). Other etiologies might be easily overlooked, leading to delayed causal treatment. One such representative is neurogenic shock following upper cervical spine fractures after minor impact trauma in the elderly with little data on prevalence and risk factors, a drawback that we address in the present study. MATERIAL AND

methodsBetween 01/2013 and 12/2023, all patients ≥ 65 years with a fracture of the first and/or second vertebra after minor impact trauma were retrospectively reviewed to evaluate the incidence and character of OHCA. Resuscitated and non-resuscitated patients were compared regarding risk factors such as age, BMI, fracture classification and displacement, cardiac illness, laboratory parameters and bone mineral density.

resultsFinal data included 141 patients, 82.5 ± 7.6 years; 73 female and 68 male. The OHCA incidence was 9.9%. Pulseless electrical activity (PEA) (71,4%) and asystole (28.6%) were the only initial cardiac rhythms in these resuscitated patients. Patients were resuscitated for 14.4 ± 9.5 min before the return of spontaneous circulation (ROSC). The in-hospital survival rate was 21.4% (n = 3). Younger patient age (OR0.992 per year), a Anderson type II odontoid fracture (OR 1.145), as well as trauma during nighttime (6 pm–7am) significantly predicted OHCA (p < 0.05). Sex, BMI, bone density, fracture displacement and laboratory parameters (serum electrolytes (Sodium and Potassium), Lactate, pH, Hemoglobin, and Creatinine) revealed no direct impact on the likelihood to suffer from OHCA.

conclusionsWith an occurrence of almost 10%, OHCA resulting from an upper cervical spine injury following low impact trauma is frequent in the elderly patient, and appears to be associated with non-shockable primary rhythms (PEA or asystole). If cardiac output is successfully restored, clinicians should always exclude an upper cervical spine fracture (especially an odontoid fracture). We therefore recommend an interdisciplinary primary assessment and cervical spine immobilization.
