Article in Journal of medical toxicology : official journal of the American College of Medical Toxicology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04996264 (Randomized, Double-Blinded, Placebo-Controlled Study to Evaluate the Safety, Tolerability, and Efficacy of a Multi-Dose Regimen of Oral Varespladib-Methyl in Subjects Bitten by Venomous Snakes), which is not on this map.

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.

Abstract

The American College of Medical Toxicology established the North American Snakebite Registry (NASBR), a national database of detailed, prospectively collected information regarding snake envenomation in the United States, in 2013. This report describes the epidemiology, clinical course, and management of snakebites in the NASBR. All cases entered into the NASBR between January 1, 2013 and December 31, 2015 were identified. Descriptive statistics are used to report results. Fourteen sites in 10 states entered 450 snakebites. Native species comprised 99% of cases, almost all of which were pit viper bites. 56.3% were identified as rattlesnakes and 29.4% as copperheads. 69.3% were male and 28.2% were children age 12 and under. Fifty-four percent of bites were on the lower extremity. Twenty-seven percent of patients with lower extremity bites were not wearing shoes. Common tissue findings associated with envenomation were swelling, ecchymosis, and erythema. Systemic effects and hematologic toxicity were more common in rattlesnake than copperhead or cottonmouth envenomations. Crotalidae Polyvalent Immune Fab antivenom was given to 84% of patients. Twelve patients (4.3%) were re-admitted to the hospital after completion of treatment. Eight were re-treated with antivenom. The NASBR gathers detailed data on venomous snakebites across the US. In its initial years, useful information has already been gained. Data regarding footwear will inform public health interventions and education, and information regarding the clinical presentation may help physicians better anticipate effects and manage snakebite. As the number of cases in the NASBR grows, associations between patient-related factors and outcomes may be studied.
