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

backgroundThe Kingdom of Saudi Arabia (KSA) was the fourth country in the world to authorize the BNT162b2 coronavirus disease 2019 (COVID-19) vaccine, which it rolled out on December 17, 2020 and first targeted at healthcare workers (HCWs). This study assesses vaccine uptake among this group during the first month of its availability.

methodsA national cross-sectional, pilot-validated, self-administered survey was conducted among HCWs in the KSA between December 27, 2020 and January 3, 2021. The survey included sociodemographic details, previous contact with COVID-19 patients, previous infection with COVID-19, receiving (or registering with the Ministry of Health website to receive) the COVID-19 vaccine, sources of HCWs' information on vaccines, awareness of emerging variants of concern, and anxiety level using the 7-item Generalized Anxiety Disorder assessment. A descriptive bivariate analysis and multivariate logistic binary regression analysis were performed. The primary evaluated outcome was vaccine uptake.

resultsOf the 1058 participants who completed the survey, 704 (66.5%) were female, and 626 (59.2%) were nurses. Of all the respondents, 352 (33.27%) were enrolled to receive or had already received the vaccine, while 706 (66.73%) had not enrolled. In a bivariate analysis, not enrolling for vaccination was more likely in females than males (78.5% vs. 21.5%, P < 0.001), HCWs between the ages of 20 and 40 years than those >40 years (70.4% vs. 29.6%, P = 0.005), Saudi HCWs than expatriates (78% vs 22%, P < 0.001), and among HCWs who used social media as a source of information than those who did not (69.8% vs. 38.6%, P < 0.001). In a multivariate analysis, independent factors associated with uptake were being a Saudi national (aOR = 1.918, 95 %CI = 1.363-2.698, P < 0.001), working in an intensive care unit (aOR = 1.495, 95 %CI = 1.083-2.063, P = 0.014), and working at a university hospital (aOR = 1.867, 95 %CI = 1.380-2.525, P < 0.001).

conclusionsA low level of vaccine uptake was observed especially in female HCWs, those younger than 40 years old, and those who used social media as their source of vaccine information. This survey provides important information for public health authorities in order to scale up vaccination campaigns targeting these HCWs to increase vaccine enrollment and uptake.
