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
purposeRural-residing children with medical complexity (CMC) may receive fragmented care given clinician shortages in rural communities. This study characterized differences in continuity of care between rural- and urban-residing CMC, applying novel measures of geographic care continuity and assessing associations between continuity, neighborhood social disadvantage, and unplanned hospital utilization.
methodsThis retrospective cohort study analyzed 2012-2017 all-payer claims data from Colorado, Massachusetts, and New Hampshire. After identifying CMC using validated algorithms, we calculated three continuity measures: (i) primary care continuity using the Bice-Boxerman Continuity of Care Index (CoCi), (ii) geographic continuity applying the CoCi at the county-level, and (iii) proportion of clinic visits within one's home county. We specified regression models to estimate rural-urban differences and interactions between rurality and neighborhood disadvantage, and to model associations between care continuity and unplanned hospital utilization.
findingsAmong 93,948 CMC, those who were rural-residing had higher mean primary care CoCi (50.6 [95% CI: 49.6-51.6] vs. 46.9 [95% CI: 46.6-47.2] for urban-residing), lower mean county-level CoCi (66.8 [95% CI: 66.1-67.5] vs. 70.4 [95% CI: 70.2-70.6]) and a lower local care continuity (53.5% [95% CI: 52.5%-54.5% vs. 60.3% [95% CI: 60.0%-60.5%]). Neighborhood social disadvantage was a significant effect modifier of the relationship between rurality and all continuity measures. Higher care continuity was associated with lower risk of unplanned hospitalization and emergency department visits.
conclusionRural-residing CMC had higher primary care continuity than their urban-residing peers but lower geographic continuity. Several associations between rurality and care continuity were moderated by neighborhood social disadvantage, highlighting the importance of considering area-level characteristics when implementing programs and policies to support this population.
