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

Climate change associated heat stress is the major global challenge affecting the overall health and production of livestock. If the ambient temperature exceeds the thermo-neutral zone of cattle, they experience heat stress. The study aimed exclusively to explore the adaptive physiological, behavioural, metabolic, endocrine and molecular responses exhibited by crossbred (Holstein Friesian × Sahiwal) calves of Kerala to acute heat stress (treatment) and compared it with the thermo-neutral zone (control) in a climate-controlled chamber. The experimental animals were given an acclimatisation period of 10 days each in the animal holding facility and in the chamber. It was followed by experimental period of 10 days each in both the groups, from 6:00 A.M. to 6:00 P.M. under thermo-neutral zone maintained at 27 °C and acute heat stress where maximum temperature of 40 °C and relative humidity of 55-65 per cent was simulated for three hours a day.
