The effect of COVID-19 on blood donation habits.
Trial report in Transfusion, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBlood centers (BCs) rely on schools and businesses. Shelter-in-place orders closed them. This study determined how COVID-19 affected donation habits. STUDY DESIGN AND
methodsTwo periods were reviewed (May 1 through June 30, 2018 vs 2019 [control] and 2019 vs 2020 [study-COVID period]). These donations were reviewed: first-time, repeat (donation ≤ 2 years), and lapsed (no donation > 2 years); sex; age; ethnicity; and ABO blood groups at high school and college drives. Testing all donors for SARS-CoV-2 antibodies started May 18, 2020.
resultsIn the study period donations significantly increased (control P = .683, study P ≤ .0001) and comparing sex (control male P = .716, female P = .657; study male P = .004, female P ≤ .0001). In the study period there was a significant decrease in Hispanic (P = .001) and African American (P < .0001) donations also seen among high school and college drives and an increase in Caucasian (P < .0001) donations. There was a significant increase in first-time (P < .0001) and lapsed donors (P < .0001) in the study period vs control (first-time P = .087, lapsed P = .308) and a significant decrease in donors not more than 30 years (study 16-20 P < .0001, 21-30 P < .0001). There was a significant increase in all blood types in the study period (P < .0001) and in donations after implementation of SARS-CoV-2 antibody testing (P = .001).
conclusionsSignificant changes occurred in donation habits in the study vs the control periods. These included increased total donations, comparing sexes, first-time and lapsed donors, all blood types, and Caucasian donations. Significant decreases were seen in Hispanic and African American donations and those not more than 30 years old.
