A Markov Chain Model for Transient Analysis of Handoff Process in Emergency Departments.
Article in IEEE robotics and automation letters, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Transfer of care between multiple units or facilities is of significant importance for patient safety, care quality, and operation efficiency. Such transfers are often referred to as handoffs in hospitals, which need to be carried out timely, safely, and smoothly with accurate information. This paper introduces a Markov chain model to study the transients of handoff process in hospital emergency departments. The handoff process is modeled by a stochastic process with unavailability of service, which characterizes the constraints in bed capacity, staff shortage, and coordination issues, etc. For systems only allowing one transfer request waiting, the transient performance is obtained through Laplace transform and its inverse transform. Such a result is then used as a building block to study the systems allowing multiple requests waiting through an iteration process, which can reduce the computation complexity substantially. Numerical studies show that such a method can provide estimates of transient performance in the handoff process with acceptable accuracy.
