Red blood cell salvage analysis from clotted blood.
Article in Blood transfusion = Trasfusione del sangue, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 clots discovered within body cavities intra-operatively are often manually broken up and placed in an autotransfusion device to recover autologous blood cells. This study evaluated the efficiency at which these red blood cells can be recovered from clot and to determine if these cells would be free of fibrin and clumping which might pose a risk of micro-emboli. MATERIALS AND
methodsWhole blood was aliquoted into 25 mL volume samples. The blood was then allowed to clot, and after 24 hours the clotted blood was manually kneaded by hand for 1, 2, 3, or 5 minutes. One mL of the harvested blood was fixed and processed for scanning electron microscope imaging. Plasma from the rest of the sample was then separated and underwent spectrophotometry for analysis of relative free haemoglobin.
resultsBlood recovered from the clotted blood ranged from 60 to 80% as time increased from 1 to 5 minutes of kneading. Volume of erythrocytes recovered from 1 minute compared to 2 minutes was statistically significant but not significant between 2 minutes or any longer period of time. Imaging did not show any evidence of fibrin strands or significant cell fragmentation. Spectrophotometry showed a steady increase of observed absorption at 540 nm, indicative of free haemoglobin, as manual kneading time increased. DISCUSSION: Red blood cells were able to be efficiently recovered from clotted blood. Imaging studies did not show any evidence of red blood cells trapped within fibrin mesh.
