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 of the research presented is the undoubted fact that industrial boiler maintenance is essential for efficient operation and preventing failures. Traditional stress measurement methods for hanger rods (with hydraulic pressure pump) can be unreliable due to operator subjectivity. Therefore, the objective is to introduce a more accurate method for measuring the stress state of hanger rods in industrial boilers using fibre Bragg grating (FBG) sensors. The study compares traditional hydraulic pressure pump measurements with FBG sensors, which allow continuous strain measurement without shutting down the boiler. The new approach follows from the fact, that FBG sensors have been used in structural health monitoring but not in this specific application. The experimental strain measurements have been conducted on an industrial boiler hanger rod in an operational facility. The FBG sensors provided more reliable and continuous measurements compared to the hydraulic pressure pump method. After the analysis of the results obtained it has been clear that the use of FBG sensors offers a promising new approach for continuous strain measurement in boiler hanger rods, contributing to the development of diagnostic methods for estimating stress levels in industrial boilers, what is a promising conclusion.
