A follow-up study of blood donors with vasovagal reaction - Three years' experience.
Article in Asian journal of transfusion science. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimThe aim of this study was to find out the incidence of seizure recurrence among blood donors who developed vasovagal reaction (VVR). SETTINGS AND
designA prospective survey-based study conducted at the department of transfusion medicine of a tertiary care referral hospital in southern India. SUBJECTS AND
methodsAll donors who were diagnosed with VVR and loss of consciousness with or without convulsions during 3½ years study period were telephonically contacted to a maximum of 3 times. Whether they experienced a repeat episode of convulsions during 6-month follow-up period irrespective of blood donation was enquired.
resultsOut of 66 donors who were included in the study, 45 (68%) donors could be successfully contacted. One donor out of 45 (2.22%) had developed a repeat episode of seizure 5 months postdonation. However, she also had a previous history of seizures which was not revealed during the medical examination.
conclusionsOur study shows that the VVR with convulsions during blood donation can trigger a secondary episode if the donor had convulsions in their past before donation. We did not find any donor who developed a new seizure episode without a past history of seizure. However, more studies are needed to confirm the same.
