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

In order to improve the bearing strength of concrete pedestals exposed to concentric and eccentric local compressive pressure, this study investigates the application of several external confinement techniques. Concrete blocks were tested under both concentric and eccentric local pressure after being cast and externally supplemented with SHCC jacketing. The main variable was the use of steel meshes (SMs) to reinforce SHCC. These SMs vary in number (1, 2, and 3) and height-to-block height ratios (0.25, 0.5, 0.75, and 1). Furthermore, the effects of the following were investigated: the use of conventional stirrups reinforcement inside SHCC jacketing and the confinement sides of the block; the number of grooves on the substrate concrete-SHCC interface, the load eccentricity ratio (0, 0.25, and 0.39), and the steel fiber content (0, 0.5, and 1%). The bearing strength rose 17.3% when the control block was reinforced with 25 mm-SHCC jacketing. In comparison to the un-strengthened sample, the bearing strength increased by 50%, when three layers of steel meshes were used. When the block sample was reinforced from one side by the SHCC layer, the bearing strength did not increase.
