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 a human-occupied vehicle (HOV), the drop weight mechanism is used to adjust the ascent/descent motion. In this paper, a new innovation has been developed through the effective integration of a permanent magnet and an electromagnet. The main advantage of this Electromagnetic Drop Weight Mechanism (EMDW) is that it requires power to be supplied at the time of drop weight (25 kg) cut off. From Response surface methodology (RSM) using desirability approach, the design criteria for EMDW System required to drop a 25 kg weight is the combination of 20 A, 18 NOT, 106 mm coil length and 24 V DC. The difference between numerical and experimental analysis was around 7.32%. The mean effect plot analysis shows that current and number of turns of coils were found to be predominant factor in designing of EMDW. To quantify the system for working in the sea, a hyperbaric chamber test at 50 bar was carried out and the system is found to be effectively working.
