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

Infectious disease, predominately chlamydiosis, contributes significantly to the decline in health of wild koala (Phascolarctos cinereus) populations in some regions of Australia. In this study, we describe the development and evaluation of a simple, sensitive, and specific loop-mediated isothermal amplification (LAMP) assay for the detection of Chlamydia pecorum in koalas as a point-of-care diagnostic tool that can be used in any wildlife hospital and in the field on specialized instrumentation. A set of primers targeting a 188-bp region of the C. pecorum genome was designed. 100% specificity of the LAMP assay was revealed by demonstrating no cross-reactivity with 33 nontarget pathogens, and complete correlation with qPCR results for 43 clinical swabs collected opportunistically from wildlife hospitals. In sensitivity evaluations, the technique successfully detected serial dilutions of extracted C. pecorum DNA with a detection limit of 44 IFU/ml.
