1 · What the graph read from it

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.

2 · The registry

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

objectivesTo evaluate the associations between sex, age, breed and collection site on platelet count and platelet clumping in feline blood samples.

methodsCats presenting to a primary care feline hospital from January 2016 to January 2017 were recruited. Any cat undergoing blood collection for a complete blood count was eligible. Cats were excluded if they were receiving clopidogrel or aspirin, had a disease known to affect platelet function, or if they required sedation for phlebotomy. All cats had their sex, age, site of venipuncture, platelet count, degree of platelet clumping and platelet morphology recorded.

resultsIn total, 649 cats were prospectively recruited. Of these, 579 (89%) cats had no clumping observed on blood smears. A significant association ( CONCLUSIONS AND RELEVANCE: The lack of effect of collection site/technique suggests that multiple sites of collection are valid when accurate platelet counts are important. The finding of lower platelet counts in younger and female cats may highlight the need to recognize age and sex when considering the management and monitoring of platelet counts and platelet disorders. Additional studies are needed to understand breed variation.
