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

Botia striata (Rao, 1920) is high valued ornamental fish, endemic to the Western ghats of India. This fish requires standardized maturation diet following a feeding regime for it to breed in captivity. Therefore, a study was conducted over a period of 90 days, employed a 2 × 3 factorial design involving six different feeding regimes: T1 (formulated feed, twice daily), T2 (formulated feed, four times daily), T3 (frozen tubifex, twice daily), T4 (frozen tubifex, four times daily), T5 (mixed diet, twice daily), and T6 (mixed diet, four times daily). The provision of selected feeding regimes for 90 days assisted with sand substratum induced the gonadal maturation in the treated fishes (n = 360) and allowed to achieve best final maturation with the success rate of 95% in the T2 experimental group and a lower success rate of 65% in the mixed diet group. Parameters such as hepato-somatic index, gonado-somatic index, histology, and reproductive hormones (11-ketotestosterone, 17β-estradiol, follicle-stimulating hormone (FSH), leutinizing hormone (LH), low-density lipoprotein (LDL), and high-density lipoprotein (HDL)) were analyzed to evaluate male and female gonadal maturation. The relative fecundity of the experimental fishes was studied and correlated with the findings of the experiment. The fish in the T2 had relative fecundity of 247 ± 8.00 no's compared to other treatments. The findings suggest that formulated feed administered four times daily significantly enhanced gonad weight, oocyte number and diameter, addressing the challenges faced in captive breeding of the zebra loach. This study provides valuable insights for optimizing captive maturation and breeding conditions for highly demanded indigenous ornamental fish facilitating its development on a commercial scale.
