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: Rapid Response Systems are hospital-wide patient-focused systems aiming to improve recognition of acute deterioration in patients and trigger a rapid response aimed at preventing potentially avoidable adverse events such as cardiac arrest and death. In 1994, the Royal Children's Hospital in Brisbane, Australia, was one of the first institutions to adopt a paediatric rapid response system (RRS). The purpose of this study was to investigate the impacts of both introduction of a paediatric RRS and increasing RRS activations (MET dose) on hospital mortality. Methods: Prospectively collected data from institutional databases at a specialist paediatric hospital was used to determine hospital mortality rate pre- and post- implementation of the RRS. An interrupted time series model using segmented regression was utilised to assess the pre-intervention trend, as well as immediate and sustained effects of RRS implementation on hospital mortality. Univariate linear regression examined potential effects of MET dose on mortality. Results: Hospital mortality rate did not change significantly over 15 years before RRS implementation. In the first year after implementation, mortality rate fell significantly (-1.4; 95 %CI -2.27 to -0.52; p = 0.0027). For each year that passed after the intervention, there was no significant change in hospital mortality rate (Estimate: -0.08; 95 %CI -0.17 to 0.02; p = 0.11). Univariate linear regression modelling showed that with every unit increase in MET Dose, hospital mortality rate decreased by -0.13 (95 % CI: -0.27 to 0; p = 0.05). Conclusions: Utilising data from one of the earliest and longest duration single-centre cohort of paediatric MET events, this study reaffirms the association between implementation of a paediatric RRS and decreased hospital mortality. The study also provides novel evidence of the impact of MET dose on patient outcome in the paediatric population. It is recommended that factors influencing the benefit of rapid response systems in paediatric populations are further identified so that this life saving initiative can be optimised.
