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

As the dysphagia handicap index (DHI) becomes more commonly used in clinical practice as a diagnostic tool, it is essential to establish the normative value of DHI. The main purpose of this study is to determine the normative value of DHI among subjects who had no history of dysphagia or neurological disease as well as no history of head or neck malignancy. A systematic literature search was performed using PubMed, Scopus and ScienceDirect to access relevant databases and to locate outcome studies. Eligibility criteria included type of publication, participant characteristics and report of outcomes. Data analysis were conducted using meta-analysis method. Five articles were included for the final analysis. The normative value of DHI was 2.49 with confidence interval of 0.51-4.48 for a group of 323 subjects, age range of 20-86 years.
