1 · What the graph read from it

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.

2 · The registry

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 green alga Chlamydomonas reinhardtii (CR) has been explored as the live component of biohybrid microrobots due to its intrinsic motility. However, cell performance depends on physiological state, which evolves with culture age. Using optical tweezers, we quantify the rotational dynamics of individual CR cells across lag, exponential, stationary, and death phases. We reveal a clear performance trajectory: rotation speed and corresponding hydrodynamic torque peak during the mid-exponential phase and decrease as cultures mature. Additionally, counterclockwise rotation consistently generates higher hydrodynamic torque than clockwise rotation. These findings provide quantitative benchmarks linking CR's motility characteristics to growth phase, offering guidelines for designing living micromachines and establishing rotational dynamics as a sensitive proxy for cellular metabolic health.
