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
Sperm cryopreservation produces a series of physicochemical phenomena that negatively impact the function and structure of spermatozoa, including the mobilization of cholesterol from the plasma membrane. The use of attenuated total reflection-Fourier-transform infrared spectroscopy (ATR-FTIR) may be useful to measure the cholesterol efflux in goat spermatozoa. Therefore, the objective of this study was to standardize the use of ATR-FTIR to measure the efflux of cholesterol in goat spermatozoa. Standardization of the technique was carried out in three stages: (i) determination of the appropriate sperm concentration to detect cholesterol in the FTIR spectrum; (ii) determination of the minimum percentage of viable spermatozoa required to observe at least five spectral bands in common with pure cholesterol; (iii) assessment of cholesterol removal in frozen-thawed spermatozoa. Possible differences in the areas of the spectral bands were compared by one-way ANOVA. Nineteen spectra were obtained: pure cholesterol, sperm transport medium, five different sperm concentrations, and ten live/dead sperm proportions (heat and cold-killed). The lowest sperm concentration at which spectral bands were clearly identified was 13 × 10
