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

Introducing a slot into an airfoil is a passive flow control technique that enhances aerodynamic performance by manipulating the boundary layers of fluid flow. This study investigates the aerodynamic performance of a novel double-split slot design using the NACA 0018 airfoil through a detailed 2D steady-state numerical analysis. A parametric study was conducted to evaluate the influence of key design parameters, including slot outlet location, outlet width, and wedge element length, on the force coefficients and the flow structure around the airfoil. Results demonstrate that the double-split slot effectively weakened the flow separation on the suction side, at moderate to higher angles of attack (15° ≤ α ≤ 30°). The optimal slot configuration achieved a lift coefficient (C
