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

Objective: To investigate and compare the median nerve-cross sectional area at the wrist region of the dominant and non-dominant hands of high- and low- smartphone users. Method: This descriptive cross-sectional study was based on 128 human subjects conducted at Bahria University Health Sciences Karachi Campus from January to June 2022. The sample size was calculated using the method of sample size for frequency in a population www.openepi.com which is an open-source calculator, version 3-SSPropor using the following equation: Sample size n = [DEFF*Np(1-p)]/[(d Results: In this descriptive cross-sectional study on 128 subjects, the difference between the median nerve cross-sectional areas (MN-CSAs) of the dominant and non-dominant hand of the high-smartphone group was highly significant ( Conclusion: Smartphone overuse resulted in an enlarged median nerve, especially in the dominant hand.
