The molecular genetics of haemophilia A: screening for point mutations in the factor VIII gene using the restriction enzyme TaqI.
Article in Human genetics, 1991. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
A combination of Southern blotting and the analysis of polymerase chain reaction (PCR) amplified DNA fragments was used to screen the factor VIII genes of 527 haemophilia A patients for point mutations within TaqI restriction sites. Since this "directed search" strategy yielded only four gene lesions, it was concluded that its efficacy is less than that originally predicted. One novel point mutation was however found in a moderately severe haemophiliac; a CGA (Arg) to CTA (Leu) transversion at codon 2209, an evolutionarily conserved residue in the C2 domain of the factor VIII protein. The remaining three detected lesions, CGA (Arg)----TGA (Term) transitions at codons 2116, 2147 and 2307, respectively, have been reported before and are consistent with recurrent mutation at these hypermutable sites. A number of TaqI restriction site polymorphisms/rare variants were also noted. These variants appear to be population-specific but are nevertheless potentially useful in individual cases as intragenic markers for carrier detection and antenatal diagnosis.
