Prevalence of asymptomatic macrothrombocytopenia in voluntary blood donors: A multicentric study.
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
introductionMacrothrombocytopenia is a combination of thrombocytopenia and giant platelets (PLTs). It can be found asymptomatically with several genetic polymorphisms/mutations. This study aimed to assess the prevalence of macrothrombocytopenia in blood donors and to identify its geographic variation. MATERIALS AND
methodsA cross-sectional observational study was conducted in blood donors in the East, West, North, and South zones of India. Donors not eligible for blood donation were excluded. Blood was collected and analyzed by hematology analyzer. Samples with low PLT count (<1.5 lakhs/mm
resultsA total of 2574 donors were screened at four centers of different geographic zones of India. The mean age was 34.81 ± 9.32 with male: female of 34.75:1. Overall macrothrombocytopenia was found in 102 (4%) with significant zonal variation: 88 (86.3%), 4 (3.9%) in East and South, respectively, and 5 (4.9%) each in West and North regions. The peripheral smears revealed giant PLTs in all cases of macrothrombocytopenia in the South and North, 76% and 80% in the East and West, respectively. The most common blood group showing macrothrombocytopenia was B positive 41 (40.2%).
conclusionMacrothrombocytopenia shows significant zonal variation, with a maximum number of cases identified in the East zone of India. Screening and awareness of this condition are essential to counsel donors for bleeding tendencies.
