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

The excessive use of conventional medications to treat coccidiosis has led to concerns regarding drug residues in tissues and the emergence of multidrug resistance. Essential oils with anti-inflammatory and antioxidant activities may also have anticoccidial effects. The present study investigated the efficacy of D-limonene and its nanoemulsion form against Eimeria tenella in chickens. An in vitro study was conducted to evaluate the sporulation inhibitory effects of D-limonene on Eimeria tenella oocysts. Five D-limonene concentrations (0.625, 1.25, 2.5, 5, and 10% v/v) were tested alongside positive (10% formalin) and negative (2.5% potassium dichromate) controls. Each ELISA plate well was inoculated with 1200 unsporulated oocysts and incubated at 30 °C for 24, 48, and 72 h. Subsequently, samples were microscopically examined to assess sporulation inhibition and calculate the percentage of sporulated oocysts. For the in vivo study, 125 eight-day-old broiler chicks were divided into five groups of 25 birds each. The control negative group remained uninfected and untreated. The control positive group was challenged with 5 × 10
