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

This study aimed to characterize the ocular biometry of the Trichechus manatus manatus applying B-mode ultrasonography across different age groups. Twenty-two animals were assessed employing a portable ultrasound device equipped with a linear transducer. Five ocular parameters were assessed: corneal thickness (CT), anterior chamber depth (ACD), axial lens length (ALL), vitreous chamber depth (VCD), and axial globe length (AGL). Data were statistically analyzed at a 5% significance level based on normality and variance. The mean values (cm) for the right eye of calves, juveniles, and adults were, respectively, CT (0.082 ± 0.012; 0.088 ± 0.011; 0.091 ± 0.010), ACD (0.040 ± 0.005; 0.051 ± 0.008; 0.052 ± 0.007), ALL (0.345 ± 0.028; 0.367 ± 0.016; 0.414 ± 0.020), VCD (1.137 ± 0.076; 1.155 ± 0.062; 1.161 ± 0.089), and AGL (1.606 ± 0.098; 1.663 ± 0.071; 1.720 ± 0.094). Values for the left eye were CT (0.082 ± 0.012; 0.088 ± 0.012; 0.087 ± 0.011), ACD (0.041 ± 0.008; 0.048 ± 0.006; 0.052 ± 0.007), ALL (0.345 ± 0.028; 0.381 ± 0.027; 0.411 ± 0.025), VCD (1.147 ± 0.076; 1.174 ± 0.045; 1.166 ± 0.086), and AGL (1.617 ± 0.086; 1.693 ± 0.062; 1.717 ± 0.095). CT, VCD, and AGL were similar across age groups, while ACD and ALL increased with age. Positive correlations between body length and ocular parameters were significant only in calves. Ocular ultrasonography is, thus, an effective, safe, and reproducible tool for ophthalmic evaluations in T. m. manatus.
