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

purposeTo evaluate the test-retest reliability, sensitivity to detect meaningful change, and validity of a respiratory threshold (RT) method based on time-dependent breakpoints in the ratio between minute ventilation and end-tidal partial pressure of carbon dioxide (V̇

methodsHealthy male participants were recruited for a reliability (n = 42) and validity study (n = 143). Participants performed ramp cycling tests (30 W·min

resultsRT

conclusionThe RT method provides a reproducible, sensitive, and physiologically grounded approach for identifying exercise thresholds and may serve as a complementary tool for threshold detection and performance monitoring.
