Coombs-Negative Hemolytic Anemia in an Elderly COVID-19 Patient.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
COVID-19 infections are known to cause multi-organ complications. Hematological complications like autoimmune hemolytic anemia with a positive direct antiglobulin test (DAT), are commonly encountered. However, Coombs-negative hemolytic anemia is extremely rare. We report an interesting case of an elderly female with moderate-severe acute respiratory distress syndrome in the setting of COVID-19 pneumonia-causing Coombs-negative hemolytic anemia. This patient initially presented with sudden onset abdominal pain and vomiting, found to have an incarcerated inguinal hernia with small bowel obstruction (SBO) on imaging. Additionally, labs revealed positive COVID-19 antigen test and normocytic anemia. The hospital course was complicated by worsening hemolytic anemia and thrombocytopenia requiring blood products. Extensive workup for hemolysis in this patient with no prior hematological abnormalities, was negative for DAT and other conditions associated with or causative of hemolysis. At discharge, hemolytic parameters improved and on follow-up, hemoglobin returned to baseline, and repeat hemolytic parameters were normal. This case emphasizes the importance of considering SARS-CoV-2 along with other viral infections as one of the differentials for Coombs-negative hemolytic anemia.
