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

backgroundPotentially malignant disorders like oral submucous fibrosis (OSMF) often precede oral squamous cell carcinoma (OSCC). The rate of transformation of OSMF to OSCC ranges from 3 to 19%. OSMF is etiologically related to chewing of areca nut (betel nut), and the high copper content in areca nut plays an important role in the pathogenesis of the disorder. Even though many studies estimated and confirmed increased copper levels in areca nuts, studies tracing the source of the increased copper content are scarce. Interestingly, on review of agricultural literature, it was found that most of the areca nut plantations in South India commonly use a copper-based fungicide, bordeaux mixture (BM).

aimThe aim of the study was to estimate and compare the copper content in areca nuts from plantations with and without copper-based fungicide usage. MATERIALS AND

methodsFour areca nut plantations from Dakshina Kannada district, Karnataka (group A) and four plantations from Ernakulam district, Kerala (group B) were selected for the study. The plantations from Karnataka used copper-based fungicide regularly, whereas the latter were devoid of it. Areca nut samples of three different maturities (unripe, ripe, and exfoliated) obtained from all plantations were dehusked, ground, and subjected to atomic absorption spectrometry (AAS) for copper analysis.

resultsThere was statistically significant difference in the copper content of areca nuts from both groups. The areca nuts from plantations treated with copper-based fungicide showed significantly higher copper levels in all maturity levels compared to their counterparts in the other group (P < 0.05).

conclusionsThe high copper content in areca nut may be related to the copper-based fungicide treatment on the palms. These areca nuts with high copper content used in quid or commercial products may be responsible for the increasing prevalence of OSMF.
