International travel by persons with medical comorbidities: understanding risks and providing advice.
Article in Mayo Clinic proceedings, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers, 1 of them a synthesis that pooled 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.
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
objectiveTo describe the medical conditions, travel plans, counseling, and medications prescribed for high-risk international travelers. PATIENTS AND
methodsThis cross-sectional study was conducted from March 1, 2008, through July 31, 2010, in 5 clinics in the greater Boston area. We assessed all travelers seen for pretravel care and compared demographic characteristics, travel plans, pretravel counseling, and interventions for healthy and high-risk travelers (as defined by medical history or pregnancy).
resultsOf 15,440 travelers, 2769 (17.9%) were high-risk; 644 of 2769 (23.3%) were immunocompromised travelers, 2056 (74.3%) had medical comorbidities, and 69 (2.5%) were pregnant women. The median age of high-risk travelers was 47 years compared with 32 years for healthy travelers (P=.0001). High-risk travelers visited the clinic a median of 25 days (range, 10-44 days) before departure. Overall, 2562 (93.9%) of high-risk travelers visited countries with medium or high risk of typhoid fever, 2340 (85.7%) visited malaria-risk countries, and 624 (22.8%) visited yellow fever-endemic countries. Of travelers to yellow fever-endemic countries, 8 of 23 (34.8%) pregnant women and 64 of 144 (44.4%) immunocompromised travelers received yellow fever vaccine. Of eligible high-risk travelers, 11 of 76 (14.5%) received a pneumococcal vaccine, 213 of 640 (33.3%) influenza vaccine, and 956 of 2681 (35.7%) either tetanus-diphtheria or tetanus-diphtheria-pertussis vaccine.
conclusionHigh-risk travelers made up nearly 20% of patients in these travel clinics, and they mostly traveled to destinations with malaria and typhoid risk. For health care professionals caring for travelers with underlying medical problems, providing appropriate travel counseling and making vaccine decisions, such as for yellow fever, are complex. Travelers with complicated medical histories may warrant evaluation by an experienced travel medicine specialist.
