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

objectiveThe aim of this study was to compare the effects of short-term storage in two different temperatures on stability of salivary total antioxidant capacity (TAC), total oxidant status (TOS) and oxidant stress index (OSI). MATERIALS AND

methodsSaliva samples were collected from twenty healthy volunteers for the study. An aliquot was selected for immediate analysis and the rest was stored at -20°C and -80°C for a period of 120 days, and analyzes were performed at 15, 30, 45, 60, 90 and 120 days. The determination of the TOS and the TAC were performed by colorimetric methods.

resultsThe results show that the two storage temperatures were able to preserve oxidants and antioxidants up to 60 days with similar levels when compared with fresh samples. When comparing the different storage temperatures at each time point, no significant differences were observed. Finally, the OSI remains constant over time of storage at both temperatures without statistically significant differences between them. The results were expressed as mean ± standard error of mean. Statistical analysis was performed using the repeated-measures analysis of variance (ANOVA), the Bonferroni and t-test. A p-value <0.05 was accepted to be statistically significant.

conclusionThe two temperatures were able to keep salivary TOS and TAC levels similar to fresh saliva samples. Therefore they are reliable for assessing oxidative stress up to 60 days.
