Towards effective coverage of Chagas disease: a community-based approach in migrant populations.
Article in International journal for equity in health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCommunity-based approaches have proven effective in improving early access to diagnosis for Chagas disease (CD). This study aimed to assess whether such strategies could reduce the number of patients lost to follow-up and contribute to the detection of concomitant Strongyloides stercoralis infection.
methodsThe intervention was implemented at the Consulate General of Bolivia in Barcelona and began with awareness-raising activities about CD. The Public Health and Community team (eSPiC) subsequently offered on-site serological screening for CD, as well as diagnostic confirmation, antiparasitic treatment, and follow-up at the Drassanes-Vall d'Hebron International Health Unit (USIDVH).
resultsOf the 325 participants, 96.3% were adults of Bolivian origin residing in Catalonia, Spain. The mean age was 43 years, and 64.3% were women. Forty-two participants (13.5%) tested positive for CD and received a follow-up appointment. Of these, 22 (52%) attended the consultation; 10 (45.5%) completed antiparasitic treatment; 4 (18.2%) had been previously treated; 2 (9.1%) were not treated due to medical decision; and 6 (27.3%) were lost to follow-up.
conclusionsThis study suggests that community-based follow-up strategies are advisable, particularly among middle-aged women with primary or secondary education. They facilitate a comprehensive continuum of care-from on-site screening to treatment adherence-which is essential for achieving the Chagas disease targets of the World Health Organization's Road Map for Neglected Tropical Diseases by 2030.
