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

purposeColor blindness is one of the potential disabilities affecting the ability of color perception by the eye. The aim of the present study was to evaluate the prevalence of color blindness among dental professionals.

methodsFor the present study, a total of 198 dental professionals were randomly selected as subjects who were asked to fill the required questionnaire followed by which their color vision status was evaluated using the Ishihara test. The results obtained were subjected to statistical analysis. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) version 17.0 (SPSS Inc., Chicago, IL, USA). The prevalence of color blindness, age specificity, and the ratio of the occurrence of color blindness in relation to gender were assessed using Chi-square test for independence and Chi-square test with Yates's correction for independence when the expected frequency was <5.

resultsThe present study reported 3.54% prevalence of color blindness among the study population. A higher number of cases were reported from males (9.26%) than females (1.39%). (

conclusionThe present study reported high prevalence of color blindness in dental professionals while they were totally unaware of it.
