Healthcare Provider Confidence and Perceived Barriers to Diagnosing Illness Associated with Harmful Algal Blooms.
Article in AJPM focus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Introduction: Illnesses caused by harmful algal blooms can vary in clinical presentation and severity depending on the types of algae, cyanobacteria, or toxins involved as well as the route and extent of exposure. These illnesses are primarily diagnoses of exclusion owing to lack of access to clinical testing for harmful algal bloom toxins. We used a national survey of healthcare providers to explore self-reported confidence and perceived barriers to diagnosing harmful algal bloom-associated illnesses. Methods: We conducted a descriptive analysis (SAS 9.4) of 2 questions from a national survey of healthcare providers administered September 14-October 26, 2020 (N=1,503). Chi-square tests were used to assess differences between groups, with statistical significance defined as Results: Most (68%) providers reported little to no confidence in their ability to identify illnesses caused by harmful algal blooms, 17% were confident or very confident, and 15% reported not seeing patients with these illnesses. Responses differed by specialization, work setting, sex, experience, whether pediatric patients were seen, and number of patients seen. Respondents regularly using resources such as newspapers (31%), professional societies (29%), and government health agencies (26%) reported increased confidence. Of 1,283 (85%) respondents who were asked about barriers to accurately diagnosing patients with these illnesses, 71% selected lack of knowledge about harmful algal bloom-associated illnesses as a barrier. Conclusions: Provider confidence in identifying harmful algal bloom-associated illnesses was low, and lack of knowledge was identified as a primary barrier, suggesting that more outreach and education are needed. Tailoring information for specific provider audiences and providing it through highly frequented channels could increase providers' confidence in identifying and diagnosing harmful algal bloom-associated illnesses.
