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

backgroundSalivary pH plays a significant role in the pathogenesis of various oral diseases and conditions. Chewing of areca nut and various tobacco products changes salivary pH.

aimThe aim of the study was to measure the effect of habitual chewing of areca nut and various tobacco products on salivary pH. MATERIALS AND

methodsThe present study included 360 individuals (chewers and nonchewers) of age group between 20 and 30 years who visited the Outpatient Department of Hi-Tech Dental College and Hospital. The patient's salivary pH was measured with the help of a digital pH meter before and after chewing areca nut and various tobacco products.

resultsIt was observed that, in all the groups of chewers, pH decreased after chewing except in the gutkha and lime chewing group, where pH increased (pH before chewing was 7.43 ± 0.41 and after chewing was 7.51 ± 0.399), the difference was strongly significant (

conclusionpH is altered in areca nut and various tobacco chewers, rendering the oral mucosa vulnerable to the toxic effects of areca nut and various tobacco products.
