Observational study in Atencion primaria, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 evaluate the results obtained by a surveillance network on arbovirosis composed by doctors and nurses located at hospitals and Primary Care trained in their identification, diagnostic confirmation and clinical management. LOCATION: North Metropolitan Area of Barcelona (1,400,000 inhabitants; Catalonia; Spain) during a calendar year.
participantsSeven Primary Care and 10 hospital physicians plus 4 Primary Care nurses. TYPE OF STUDY: A prospective observational study. MAIN MEASUREMENTS: Demographic, epidemiological (autochthonous/imported, suspect/probable/confirmed case) and healthcare variables (symptoms, serological profile, viral period) were defined.
resultsOf the 34 patients identified, 26 (76.5%) met study criteria. Among them, any arbovirosis was confirmed in 14 (53.8%): 13 dengue plus 1chikungunya fever. There were no cases of Zika fever. There was a history of travel to endemic areas 23 (88.4%), but not in 3cases (11.6%) in which the possibility of an indigenous transmission was considered; of them, a case of dengue was confirmed. The estimated incidence of arbovirosis was 0.4 (95%CI: 0.33-0.51) cases ×10,000hab/year which, when compared to the estimated incidence in the same geographical area during the period 2009-2013 (0.19cases ×10,000hab/year; 95%CI: 0.07-0.31), a significant increase was found (P=.044). Patients within viremia period at the time of their first medical visit were 11 (42.3%).
conclusionsAn intensified epidemiological surveillance program defined at Primary Care and hospital levels is able to detect significantly more cases of imported and autochthonous arbovirosis. Possibly we are witnessing an increase in the incidence of imported arbovirosis and, thus, measures aimed at their identification and confirmation should be reinforced.
