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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBlood transfusion is an integral part of the health-care system. A healthy donor is important for safe blood transfusion. Donors are selected based on the deferral criteria given by the Drugs and Cosmetics Act 1940 and amended thereof. Coronavirus disease 2019 (COVID-19) vaccination became mandatory after the spread of COVID-19 pandemic and was included in the deferral criteria.
objectiveThe objective was to study and analyze the impact of COVID-19 vaccination on the deferral pattern in blood donors. MATERIALS AND
methodsA retrospective study was carried out in the Department of Immunohematology and Blood Transfusion for pre-COVID period from January 2019 to December 2019 for the most common reason of deferral before COVID-19 and for comparison for donor deferral with COVID-19 period. Then, a retrospective study was carried out over a period of 12 months from February 2021 to January 2022. The demographic details of donors such as age, gender, voluntary or replacement donation, and temporary and permanent reasons for deferral were recorded. The data were entered in the MS Excel sheet and descriptive statistics were calculated.
resultsThe total numbers of registered donors were 7064. Six thousand two hundred and sixty-four donors were accepted for donation, of which voluntary donations were 4478 (71.48%). The deferred donors were 800 (11.3%). Seven hundred and thirty-eight (92.26%) deferred donors were male; the most common cause of temporary deferral was COVID-19 vaccination 179 (22.37%), followed by low hemoglobin 162 (20.25%). The common causes of permanent deferral were high blood pressure 36 (5.17%) and history of unknown jaundice 10 (1.43%).
conclusionCOVID-19 vaccination had a significant impact on the pattern of donor deferral. However, this was only a temporary situation till the pandemic is over. The loss of potential donors has adversely impacted the transfusion services.
