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

purposeThe present study aimed to assess the prevalence of tasters and non-tasters among children using a 6-n-propylthiouracil (PROP) taste test, and to investigate the association between taste predisposition, caries experience severity, oral hygiene practices, and dietary habits.

methods200 children aged 7-10 years underwent a PROP filter paper taste test. Dental caries experience was assessed using the ICDAS system, and data on oral hygiene and dietary habits were collected via a questionnaire. A training form was implemented to ensure comprehension of the general labelled magnitude (gLMS) scale. Scores on this scale were used to categorise individuals into super-tasters, medium tasters, and non-tasters.

resultsSuper-tasters were the most prevalent genetic taste sensitivity phenotype (54.0%), followed by non-tasters (23.5%) and medium tasters (22.5%). Non-tasters demonstrated higher caries experience and severity, compared to tasters (p < 0.001). Non-tasters were three times more likely to snack frequently and had lower brushing frequency. Tasters reported fewer snacking occurrences.

conclusionNon-tasters, identified by the PROP sensitivity test, had higher caries experience, more frequent snacking and soft drink consumption and less frequent brushing.
