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

Variant calling in segmental duplications is challenging for short-read sequencing because of ambiguous read origins. We present SDrecall, a method for sensitive variant detection in these regions. Upon constructing a network of homologous sequences, SDrecall realigns reads to each segmental duplication from its homologous counterparts. Realignments are phased and assembled into haplotypes via graph-based algorithms, followed by integer linear programming to retain the two most plausible haplotypes. Tested against long-read benchmarks, SDrecall achieved 95% sensitivity, while maintaining manageable false positives for short variants. SDrecall thus offers significant value for molecular diagnosis in terms of causal mutation detection within homologous regions.
