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

backgroundHaemophilia A (HA) is an X-linked bleeding disorder caused by mutations in the coagulation factor Ⅷ (F8) gene. Its incidence in men is estimated to be approximately 1/5000.

objectiveThis study aimed to characterize the mutation spectrum of the F8 gene in 485 Chinese families, encompassing all HA phenotypic classes. Additionally, we evaluated the accuracy of prenatal diagnosis of foetuses at risk of having HA.

methodsLong-Distance PCR (LD-PCR) and Multiplex PCR were used to detect inversions, next-generation sequencing (NGS) was used for point mutations, and multiplex ligation-dependent probe amplification (MLPA) was used for large deletions or duplications.

resultsA mutation spectrum of 478 HA families was produced. Throughout 26 exons and 15 introns, a total of 237 different alterations of mutations were detected, of which 146 are known mutations (64.5%) and 91 are novel mutations (35.5%). Prenatal diagnosis revealed 97 normal males (35.79%), 103 HA males (38.01%), 36 normal females (13.28%), and 38 HA carrier females (14.02%).

conclusionUsing a systematic approach comprised of three steps, 237 pathogenic variants in 478 out of 485 patient samples (98.6%) were detected, including the identification of a heterogeneous mutation spectrum of 91 novel mutations. In addition, prenatal diagnosis of HA in pregnant carriers allowed for accurate determination of the foetal F8 gene state.
