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

The scarcity of natural resources worldwide has encouraged the reuse of industrial waste in cementitious materials. In this context, waste foundry sand (WFS) is a promising material for replacing common sand (CS) in non-structural mortars. This study reviews the literature on mortars containing WFS through a structured search and selection process. The review evaluates the mechanical properties of mortars considering WFS characteristics, mix proportions, specimen geometry, and workability conditions, while also discussing sustainability, circular economy benefits, and potential environmental risks. The reviewed literature revealed inconsistencies in the mechanical performance of mortars containing the same WFS replacement level. The reduction in compressive strength (CS) showed a low linear correlation with replacement level (R
