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

Male blue catfish (Ictalurus furcatus) mature at 4-7 years and cannot be hand-stripped, making sperm collection a lethal procedure. Sperm are also highly variable in quality/quantity. We monitored blue catfish males for 34 months (2.3 to 4.9 years old; y/o) to quantify changes in body morphometrics, plasma androgens, osmolality, ions, testicular development, and gene expression. Body weight and length of fish ranged from 0.6 ± 0.2 to 3.2 ± 0.2 kg and 35.2 ± 2.1 to 58.9 ± 1.9 cm, respectively. Testes weight and gonadosomatic index (GSI) were highly variable within/between sampling points. Maximum testes weight was 6.95 g (4.7 y/o) and GSI was 39.9% (3.7 y/o). Age-associated changes in testicular development were significant, with highest spermatogenic maturity values (0.31-0.73) reported for 3.11 to 4.9 y/o fish and lowest for 2.3 (0.13) and 2.11 (0.12) y/o fish. Spermatozoa were observed in 3.3 and 4.2 to 4.9 y/o fish. The highest ratio of spermatozoa was detected at 4.2 y/o (70%). Androgens spiked at 3.11 y/o, coinciding with reproductive season. An increase in osmolality (mOsm/kg) was observed for 3.11 to 4.5 y/o fish, then decreased. K
