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
Bone marrow examination entails study of aspirate smears, touch imprints and trephine biopsy. Bone marrow aspirate smears can be prepared by the squash (crush) or wedge method. Both techniques have their own advantages and disadvantages. There is paucity of studies that have compared these smear types. This study was conducted over a period of one year. Two hundred and five bone marrow aspirates were included. Both squash and wedge smears were made. Blinded slide review was done. Bone marrow cellularity, megakaryocyte number, myeloid to erythroid (M:E) ratio, morphology and final diagnosis on each smear type was compared. Chi square test, t-test and Kappa were applied to study the agreement between the wedge and squash smears. Among the 205 patients studied, squash smears showed significant over estimation of cellularity and megakaryocyte number (
