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
We analyzed mitochondrial (mt) DNA restriction fragment length polymorphisms (RFLPs) associated with cytochrome oxidase, subunit I (coxI)-related gene sequences in 268 trees derived from 19 natural populations of three species of pines from California (USA): Monterey pine (Pinus radiata D. Don), bishop pine (P. Muricata D. Don), and knobcone pine (P. attenuata Lemm.). Total genomic DNA was digested with four restriction endonucleases and probed with a 750-bp fragment of the mitochondrialcoxI gene amplified fromP. attenuata via the polymerase chain reaction (PCR). ThecoxI gene is repeated at least 4 times in some populations, and all variants that we observed resulted from complex rearrangements rather than from point mutations. There was limited intrapopulation variation, but strong differentiation among populations. When applied to haplotype frequencies, Nei's gene diversity within populations (Hs) averaged 7% (±3), and Gst varied from 75% forP. Radiata to 96% forP. muricata. The high degree of population differentiation for mtDNA suggests that it can be a powerful marker of population differences, but its rapid rate of structural evolution appears to result from recombination among a limited number of repetitive elements-giving frequent homoplasious fragment phenotypes. The phylogenetic trees disagreed with results from chloroplast DNA, nuclear gene, and morphological studies.
