Effect of usual source of care on depression among Medicare beneficiaries: an application of a simultaneous-equations model.
Article in Health services research, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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 investigate whether having a usual source of care (USOC) resulted in lower depression prevalence among the elderly. DATA SOURCES: The 2001-2003 Medicare Current Beneficiaries Survey and 2002 Area Resource File. STUDY
designTwenty thousand four hundred and fifty-five community-dwelling person-years were identified for respondents aged 65+, covered by both Medicare Parts A and B in Medicare fee-for-service for a full year. USOC was defined by the question "Is there a particular medical person or a clinic you usually go to when you are sick or for advice about your health?" Ambulatory care use (ACU) was defined by having at least one physician office visit and/or hospital outpatient visit using Medicare claims. Depression was identified by a two-item screen (sadness and/or anhedonia). All measures were for the past 12 months. A simultaneous-equations (trivariate probit) model was estimated, adjusted for sampling weights and study design effects. PRINCIPAL
findingsBased on the simultaneous-equations model, USOC is associated with 3.8 percent lower probability of having depression symptoms (p=.03). Also, it had a positive effect on having any ACU (p<.001). Having any ACU had no statistically significant effect on depression (p=.96).
conclusionsUSOC was associated with lower depression prevalence and higher realized access (ACU) among community-dwelling Medicare beneficiaries.
