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

This work presents a compact, low-power fully CMOS pulse-frequency-modulation (PFM) temperature sensor fabricated in 180 nm technology, supporting a wide -60 °C to 120 °C sensing range. Subthreshold biasing generates temperature-proportional current, while PFM converts current variations into digital pulse signals to bypass supply voltage swing limitations. The following two core optimizations are proposed: an improved cascode current mirror to suppress channel-length modulation and stabilize thermal current, and a temperature-insensitive monostable circuit eliminating extreme-temperature oscillation failure caused by variable reset pulse width. A four-point off-chip calibration model further compensates static and temperature-dependent loop delay errors. The prototype occupies only 2200 μm
