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 inability to distinguish males from females in young birds is a major obstacle for pair formation in reintroduction-restocking programs and commercial-amateur breeding. Several techniques are employed to address this problem, but not all of them are suitable for juvenile subjects. Among the various tests applied for sex determination, polymerase chain reaction (PCR) is one of the genetic tools that seems to be most effective (rapid, not invasive and cheaper). In this study, DNA was extracted from down and feathers to make the procedure less stressful for nestlings. The DNA was amplified by PCR, and the amplicon was subjected to the restriction endonucleases procedure when the gender was not clearly identified by PCR alone. One hundred and fifty-three avian species were sexed using this procedure, including 27 for the first time. In all the nestlings and juveniles tested, sex was correctly identified; in fact, all pairs that reached sexual maturity during this study gave offspring.
