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

Two proteins that differ at the N terminus (l-KlCpo and s-KlCpo) are derived from KlHEM13, a single-copy-number gene in the haploid genome of Kluyveromyces lactis. Two transcriptional start site (tss) pools are detectable using primer extension, and their selection is heme dependent. One of these tss pools is located 5' of the first translation initiation codon (TIC) in the open reading frame of KlHEM13, while the other is located between the first and second TICs. In terms of functional significance, only s-KlCpo complements the heme deficiency caused by the Δhem13 deletion in K. lactis. Data obtained from immune detection in subcellular fractions, directed mutagenesis, chromatin immunoprecipitation (ChIP) assays, and the functional relevance of ΔKlhem13 deletion for KlHEM13 promoter activity suggest that l-KlCpo regulates KlHEM13 transcription. A hypothetical model of the evolutionary origins and coexistence of these two proteins in K. lactis is discussed.
