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

Gastrointestinal worm infections (GWI) constrain pig production and zoonotic pig parasites make pork unsafe for human consumption. This study determined the distributions, determinants and dynamics of GWI and also the effect of the infection on production parameters in pigs reared in Enugu State, Nigeria. The GWI were determined by faecal egg counts following standard procedure. Sixty piggeries and 564 pigs were randomly selected for the study. Questionnaire survey was conducted to obtain data on some production parameters and risk practices aiding GWI in the piggeries. An overall prevalence of 88.3% (53/60) and 68.1% (384/564) at farm and individual pig levels respectively were recorded. High egg counts of single and mixed infections involving SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s12639-021-01377-y.
