Effect of tablet tilt positioning on ergonomic risks and respiratory function.
Article in Heliyon, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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 static posture associated with continuous tablet use can lead to musculoskeletal disorders of the neck and upper extremities as well as respiratory function disorders. We hypothesized that 0-degree tablet placement (flat on a table) would affect ergonomic risks and respiratory function. Eighteen undergraduate students were divided into two groups (n = 9 per group). In the first group, the tablet was placed at a 0-degree angle, whereas in the second group, it was placed at a 40- to 55-degree angle on a student learning chair. The tablet was used continuously for 2 h for writing and internet use. Rapid upper-limb assessment (RULA), craniovertebral angle, and respiratory function were assessed. There was no significant difference in respiratory function, including forced expiratory volume in 1 s (FEV
