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
Background: E-consults for outpatient stroke/TIA care can improve timeliness of neurologic care. For rural Veterans, many of whom are eligible for VA-paid community care, it is unknown whether active implementation of an e-consult within the Veterans Health Affairs (VA) heath system impacts the overall volume of outpatient stroke care provided in the VA vs. in non-VA community care. Methods: We studied the implementation of an e-consult for outpatient stroke/TIA care in a stepped-wedge trial in 10 VA facilities in the VA National TeleNeurology Program (NTNP). Sites were randomized to one of three sequential six-month active implementation waves (after two months of usual care where the e-consult was available) that included a stroke prevention lecture for primary care (PC) providers, as well as participation in monthly PC meetings to review cases and utilization of the consult. After the six-month active implementation (sustainability period), no data were presented to PC teams. The primary outcome was whether a consult was placed in the VA vs. community care neurology (CCN) for outpatient stroke/TIA care. A generalized linear mixed model (GLMM) with binomial distribution and log link fit to the primary outcome was used to estimate the effect of active implementation with baseline serving as the reference. Other effects in the model included Results: Of the 1,680 consults placed for stroke/TIA, 22% (365/1,680) were NTNP (within VA). The GLMM model demonstrated that the odds of a stroke/TIA consult being placed within the VA increased during active implementation: OR 1.92 (1.17-3.16, Conclusion: Active implementation of a VA stroke/TIA e-consult may increase the proportion of neurology consults placed to VA compared to community care. Further implementation efforts to sustain this effect and better understand factors influencing patient and provider choices about where to receive care are needed.
