Differences in Prevalence of Large Polyps Between Hispanic Americans from Mexican- and Non-Mexican-Predominant States.
Article in Digestive diseases and sciences, 2019. 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
backgroundThere have been conflicting reports comparing the prevalence of large polyps (>9 mm) between Hispanics and non-Hispanic whites (NHW). Differences between Hispanic subpopulations may account for these variations.
aimsWe aimed to assess the prevalence of large polyps (>9 mm) in Hispanics from Mexican- and non-Mexican-predominant states compared with NHW. As secondary outcome, we evaluated results by polyp location.
methodsThe 2010 U.S. Census Bureau was used to identify states with a predominantly Mexican Hispanic (West) versus non-Mexican Hispanic (East) populations. Average-risk colonoscopies in those states from 2001 to 2014 were accessed using the Clinical Outcomes Research Initiative database. Military and Veteran's Administration sites were excluded. Hispanics were compared with NHW in each geographical location using hierarchical logistic regression analysis.
resultsA total of 65,138 procedures were included with 33,425 procedures in the West (14.5% Hispanics) and 31,713 procedures in the East (44.0% Hispanics,). East Hispanics had significantly less odds of large polyps, OR 0.74, CI 0.58-0.94, p = 0.02, while West Hispanics exhibited no difference, OR 0.91, CI 0.76-1.10, p = 0.33, compared with NHW. Eastern Hispanics had less odds of large distal polyps, OR 0.69, CI 0.52-0.91, p = 0.01, and no difference in proximal polyps compared with NHW. Among Western Hispanics, no differences were seen in proximal, OR 1.06, CI 0.83-1.35, p = 0.66, or distal polyps, OR 0.83, CI 0.68-1.02, p = 0.08, compared with NHW.
conclusionUsing NHW as a reference, Hispanics from Mexican-predominant states have a similar prevalence of large polyps, while Hispanics from non-Mexican-predominant states have a lower prevalence. Differences in Hispanic subpopulations likely explain previous conflicting reports on the prevalence of large polyps in Hispanics and NHW.
