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
Voltage-dependent inactivation of ion channels contributes to the regulation of the membrane potential of excitable cells. Mouse polycystic kidney disease 2-like 1 (PKD2L1) forms voltage-dependent nonselective cation channels, which are activated but subsequently inactivated in response to membrane depolarization. Here, we found that the mutation of an asparagine 533 residue (N533Q) in the outer pore loop region of PKD2L1 caused a marked increase in outward currents induced by depolarization. In addition, the tail current analysis demonstrated that the N533Q mutants are activated during depolarization but the subsequent inactivation does not occur. Interestingly, the N533Q mutants lacked the channel activation triggered by the removal of stimuli such as extracellular alkalization and heating. Our findings suggest that the N533 residue in the outer pore loop region of PKD2L1 has a key role in the voltage-dependent channel inactivation.
