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

Background: Human granulocytic anaplasmosis (HGA) is an emerging tick-borne zoonosis caused by Methods: Between 2019 and 2025, for each HGA PCR request at the Colmar Civil Hospitals, two May-Grünwald Giemsa-stained BS were prepared, digitized, and the cells preclassified using the CellaVision® System systematically. Retrospectively, two microbiologists performed a review of the recorded images for all positive HGA PCR results to identify intragranulocyte morulae independently and blinded to each other's findings. Results: A total of 101 PCR tests for HGA were performed in 92 patients, with 5 patients testing positive (median time to results: 6 days). In all 5 patients, images of intragranulocyte morulae were obtained using the CellaVision® system, and the examination was completed in under 15 min. Conclusions: Using the CellaVision® system for BS analysis with a standardized review protocol simplifies the reading process. The method successfully detected morulae in all confirmed cases included in this preliminary study though prospective validation is still required. However, a negative digitally assessed blood smear must not be interpreted as excluding HGA.
