Screening for mutations in exon 4 of the LDL receptor gene in a German population with severe hypercholesterolemia.
Article in Human genetics, 1995. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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 group of 218 patients with severe hypercholesterolemia (LDL cholesterol > 260 mg/dl) living in the Cologne area were screened for mutations in the 3 half of exon 4 of the low density lipoprotein (LDL) receptor gene by the single-strand conformation polymorphism (SSCP) method. The analysed fragment was 242 bp in length and comprised approximately 6% of the coding region. In 11 patients an abnormal SSCP pattern was observed. Two of the abnormal fragment patterns were identical. The results of the SSCP screening could be confirmed by direct DNA sequencing. Three of the ten different mutations were previously described (3 bp deletion: codon 197; Asp200-->Gly; Glu207-->stop). Of the newly identified mutations there were two deletions, two insertions, one combined insertion and deletion mutation and two single base pair substitutions [1 bp deletion: G in codon 197; 37 bp deletion: T in codon 196-208 or AT in 196-207 and GA in codon 208; 18 bp insertion: codon 201-206; 8 bp insertion: codon 155-156 and GA in codon 157; 6 bp insertion (codon 196-197) and 5 bp deletion (codon 199, C in codon 198 and G in codon 198 or 200); Asp200-->Tyr; Asp203-->Val]. The 8-bp insertion was detected in a second unrelated individual. The analysis of the functional consequences of the mutations indicates that all mutations were causative of the LDL cholesterol elevation.
