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

backgroundThe National Institutes of Health Stroke Scale (NIHSS) quantifies stroke severity, yet variability in its reporting may reflect healthcare disparities and affect outcomes. This study analyzes trends in NIHSS reporting in the National Inpatient Sample (NIS) database and its relationship with patient characteristics and outcomes.

methodsThis retrospective cross-sectional study used data from the NIS between May 2016 and December 2022. This nationally representative sample included patients in the US hospitalized with acute ischemic stroke (AIS). Primary outcomes include NIHSS reporting rate over time, factors associated with reporting, and subsequent discharge disposition. Propensity score matching (PSM) accounted for patient demographics, hospital characteristics, severity of illness, and use of reperfusion therapy.

resultsAmong 4,558,909 AIS hospitalizations, NIHSS was reported in 1,930,880 (42.4%). The proportion of hospitalizations with reported NIHSS increased from 14.33% in December 2016 to 56.27% in December 2022. After PSM, reporting of NIHSS was associated with higher odds of routine discharge (Adjusted Odds Ratio = 1.03, 95% CI: [1.01-1.04]; p < 0.001) and lower odds of inpatient mortality (0.650 [0.632-0.668], p < 0.001). Scores were less likely to be reported in females (0.970 [0.961-0.979], p < 0.001) and Black (0.963 [0.939-0.988], p = 0.004) or Hispanic patients (0.960 [0.926-0.996], p = 0.030), as well as in smaller and less urban hospitals. DISCUSSION: Since the implementation of NIHSS reporting, rates have increased to more than half of all AIS hospitalizations as of December 2022. NIHSS reporting was significantly associated with improved discharge disposition, and patient demographics impacted odds of having a reported NIHSS, highlighting persistent disparities in stroke care.
