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 calcitonin (CT)/calcitonin gene-related peptide I (CGRP-I) gene (CALC-I gene) is subject to alternative tissue-specific processing of its primary transcript. CT mRNA is the predominant mRNA produced in thyroid C cells, whereas CT gene-related peptide I mRNA is the main product in neurons of the central and peripheral nervous systems. The CT-specific exon 4 is surrounded by weak processing sites. In this study we have investigated whether exon 4 sequences are involved in the tissue-specific selection of the exon 4 splice acceptor site. The results indicate that two separate elements, termed A and B, in the 5' part of exon 4 are required for production of CT-specific RNA. These sequences are located between nucleotides 67 and 88 (A) and nucleotides 117 and 146 (B) relative to the 5' end of exon 4. Variation of the distance between these sequence elements and the 3' splice site of exon 4 does not change the processing choice. These sequence elements are functionally equivalent. CT-specific splicing requires the presence of both sequence A and B or duplicates of either sequence element in exon 4. The effect of these sequences on the RNA processing choice is overruled by mutation of the CT-specific uridine branch acceptor nucleotide into a commonly preferred adenosine residue.
