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
Lon protease 1 (LONP1) is a conserved hexameric protease implicated in mitochondrial disorders and cancer progression. In this study, we present PZL-26, a potent and selective small-molecule inhibitor that targets LONP1 without affecting the proteasome, leading to selective accumulation of mitochondrial proteins. Using PZL-26 in a whole-genome CRISPR-Cas9 screen, we identified genes essential for cell survival under protease inhibition, supporting a role for LONP1 in key mitochondrial processes, including complex I biogenesis, mitochondrial transcription, and translation. Our CRISPR screen results are consistent with proteomics analysis, with both approaches converging on the same mitochondrial pathways and highlighting functional interactions between LONP1 and other mitochondrial proteases, including potential compensatory mechanisms. These findings establish PZL-26 as an effective tool for exploring LONP1 function and pave the way for future therapeutic strategies targeting LONP1 in mitochondrial diseases and cancer.
