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
The psbB-psbT-psbH-petB-petD operon of higher plant chloroplasts is a heterogeneously composed transcriptional unit that undergoes complex RNA processing events until the mature oligocistronic RNAs are formed. To identify the nucleus-encoded factors required for the processing and expression of psbB-psbT-psbH-petB-petD transcripts, we performed mutational analysis using Arabidopsis. The allelic nuclear mutants hcf152-1 and hcf152-2 were identified that are affected specifically in the accumulation of the plastidial cytochrome b(6)f complex. In both mutants, reduced amounts of spliced petB RNAs (encoding the cytochrome b(6) subunit) were detected, thus explaining the observed protein deficiencies. Additionally, mutant hcf152-1 is affected in the accumulation of transcripts cleaved between the genes psbH and petB. As a result of a close T-DNA insertion, the HCF152 gene was cloned and its identity confirmed by complementation of homozygous mutant plants. HCF152 encodes a pentatricopeptide repeat (PPR) protein with 12 putative PPR motifs that is located inside the chloroplast. The protein shows a significant structural, but not primary, sequence similarity to the maize protein CRP1, which is involved in the processing and translation of the chloroplast petD and petA RNAs. In addition, we found that HCF152 is an RNA binding protein that binds certain areas of the petB transcript. The protein possibly exists in the chloroplast as a homodimer and is not associated with other proteins to form a high molecular mass complex.
