Effectiveness of Toothpastes on SARS-CoV-2 Viral Load in Saliva.
Article in International dental journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04537962 (Avaliação da Carga do vírus SARS-CoV-2 na Cavidade Oral e na Saliva após desinfecção Com soluções Antimicrobianas Orais e dentifrícios.), which is not on this map. Cited by 4 papers.
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.
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.

Abstract
introductionThe effect of toothpastes on viruses, such as SARS-CoV-2, is unknown. This study investigated the short-term effect of toothpastes containing antimicrobial properties in patients with novel coronavirus disease 2019 (COVID-19) to determine whether they could reduce the SARS-CoV-2 salivary viral load.
methodsHospitalised patients with COVID-19 (n = 83) were instructed to perform toothbrushing with 1 of 3 arms: a toothpaste containing 0.96% zinc (zinc oxide, zinc citrate) in a silica base (Test 1), a toothpaste containing 0.454% SnF
resultsBrushing with the Test 1 toothpaste reduced the SARS-CoV-2 salivary viral load by 4.06-fold at T1, by 2.36-fold at T2, and by 1.42-fold at T3. Similarly, brushing with a Test 2 toothpaste reduced the SARS-CoV-2 salivary viral load by 2.33-fold at T1, by 2.38-fold at T2, and by 0.77-fold at T3.
conclusionsImmediately after brushing, the use of antimicrobial toothpastes reduced the salivary viral load of patients with COVID-19. The trial was registered on https://clinicaltrials.gov/ (NCT04537962).
