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
We report a new multicolor PRINS procedure for chromosome identification on human sperm. Based on the direct in-situ mixing of the colors of the fluorochromes (FITC, TRITC, Cascade Blue) incorporated in sequential PRINS reactions, this method facilitates rapid distinct labeling of 3 or 4 chromosomes. Each PRINS reaction consists of a unique 4 minute step for annealing and elongation. The method was successfully tested on lymphocytes and spermatozoa. Estimates of disomy were performed for chromosomes 7, 9 and 16 on sperm samples from 2 healthy donors. There was no significant difference between the disomy rates obtained with the conventional two-color PRINS technique and this new three-color procedure. By simplifying the multicolor PRINS protocol, this new protocol should facilitate the use and adaptation of PRINS to various cytogenetic applications.
