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

purposeThis computed tomography study aimed to display the alteration in the coccyx morphology (its ossification process, dimension and angulation) in children with advancing age.

methodsPelvic radiologic scans of 180 children aged 1-18 years were retrospectively evaluated to observe changes in the coccyx morphology with age, and to measure the linear length (LL), curvilinear length (CLL), sacrococcygeal angle (SCA), and intercoccygeal angle (ICA).

resultsThe present study divides the postnatal evolution of the coccyx into three phases as follows: (a) in the first stage when the coccyx is of the shortest, it is completely cartilage until the age of 2 (infancy period) and its first segment begins to ossify by the age of 3 (early childhood period), (b) in the second stage when the coccyx is of medium size, its first segment is completely ossified by the age of 6 (late childhood period) and the ossification of its all segments is completed from the age of 11 (prepubescent period), and (c) in the third stage when the coccyx is of the longest, it reaches to adult size (postpubescent period). Linear functions were calculated as y = 15.647 + 1.145 × age (p < 0.001, R

conclusionConsidering that morphological features of the coccyx, such as ICA, can be used in the diagnosis of coccydynia, our dataset may facilitate the identification of children with suspected coccydynia.
