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

OBJECTIVE/

backgroundTo examine the association between ethnicity and 90-day post-stroke subjective sleepiness, an important determinant of quality of life, as measured by the Epworth Sleepiness Scale (ESS), among ischemic stroke survivors. PATIENTS/

methodsMexican American (MA) and non-Hispanic white (NHW) recent ischemic stroke patients were identified from the population-based Brain Attack Surveillance in Corpus Christi Project (2010-2016). Subjects completed a baseline interview and 90-day outcome assessment that included the ESS. Excessive daytime sleepiness was defined as an ESS >10. Tobit regression models were used to assess associations between ethnicity and ESS unadjusted and adjusted for multiple potential confounders.

resultsAmong 1,181 (62.5% MA) subjects, mean ESS at 90 days was 8.9 (SD 6.0) among MA and 7.4 (SD 4.9) among NHW subjects: 1.45 (95% CI: 0.75, 2.15) points higher among MA than NHW subjects. After adjustment, mean ESS at 90 days was 1.16 (95% CI: 0.38, 1.94) points higher among MAs than NHWs. The prevalence of excessive daytime sleepiness was 39% among MA and 30% among NHW subjects (p = 0.0013).

conclusionsNinety days after stroke, sleepiness is worse in MAs compared to NHWs, even after accounting for potential confounding variables. Further studies should address ways to reduce this disparity.
