1 · What the graph read from it

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.

2 · The registry

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

backgroundMissed clinic appointments disproportionately affect Medicaid-insured patients and residents of socioeconomically deprived neighborhoods. The role of the recent telemedicine expansion in reducing these disparities is unclear. We analyzed the relationship between census tract (CT) poverty level, residential segregation, missed appointments, and the role of telemedicine.

methodsThis retrospective cohort study used electronic health records (EHR) data merged with population datasets and restricted to adult patients (≥ 18 years) with completed or missed internal or family medicine outpatient clinic visits (03/2020-12/2022). Using generalized estimating equations, we analyzed the association between missed appointments, CT poverty level, CT residential segregation (operationalized using the isolation index), and appointment modality.

resultsSample size was 125,229 appointments for 68,471 unique patients (Hispanic [46.6%], White [9.4%], Black [18.7%], Asian [2.6%], Native American [1.9%], and "other race/ethnicity" [0.8%]; 18-39 years [38.2%], 40-64 years [56.4%], and > = 65 years [5.36]). There was an increased likelihood of missed appointments with increasing Hispanic isolation index (OR 1.12; 95% CI 1.03, 1.23) and decreased likelihood with increasing Black isolation index (OR 0.71; 95% CI 0.61, 0.83). The protective effect of telemedicine on missed appointments decreased with increasing Black and Hispanic isolation index.

conclusionOur results suggest that further studies are needed to understand the potential impact of telemedicine on healthcare use inequities among residents of residentially segregated areas. Targeted interventions that aim to identify and address structural factors that could limit the benefits of telemedicine use are also needed.
