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

This article includes tests of the deflection and load-bearing capacity of reinforced concrete beams exposed to chloride ions. This work forms part of the verification of a newly developed model for estimating the intensity of the corrosion current of the reinforcement, which assumes the possibility of estimating the corrosion parameter based on a detailed analysis of the element deformation. The model assumes the use of the inverse problem, which is based on the analysis of deflection as a result of the partial impact of the corrosion process on the main reinforcement in the reinforced concrete element. This article presents, in detail, the course of the conducted tests, including the results of the deflection measurements with simultaneous measurements of the intensity of the corrosion current of the reinforcement during the test. As part of this research, a gravimetric analysis of the loss of reinforcement mass caused by the ongoing corrosion process was also performed. The main objective of this research was to experimentally verify the adopted model of the new diagnostic method, which fully confirmed the model assumptions. The obtained research results confirmed the validity of the assumptions adopted in the theoretical model, which was further confirmed by analytical calculations.
