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
Herein, we show compelling evidence of structural remodeling in mitochondrial membranes of cancerous colon cells when compared to their noncancerous counterparts. The physical characteristics of cancerous and noncancerous mitochondria were systematically investigated using small-angle neutron scattering (SANS), cryogenic electron tomography (cryo-ET), neutron spin-echo (NSE) spectroscopy, and high-throughput lipidomics. Our results exhibit evidence of both mechanical softening of the mitochondrial membrane, as seen by NSE, and ultrastructure rearrangements of the inner mitochondrial membranes, as seen by SANS and cryo-ET, in cancerous cells. These differences in properties seem to be correlated with changes in the lipidome, suggesting the changes are due to the limited number of lipid classes immediately available during the rapid proliferation of cancerous cells. Finally, we highlight a mechanism by which pancratistatin (PST), a natural anticancer therapeutic candidate, may selectively induce apoptosis by altering the mechanical properties and ultrastructure of cancerous mitochondria while sparing noncancerous mitochondria. Discovery of these structural anomalies will lead to improvements in diagnostics, therapeutic development, and the advancement of targeted approaches for traditionally complex cancers which evade our current treatments.
