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

Increases in muscle temperature during exercise and passive heating are associated with beneficial outcomes. Far infrared (FIR) saunas are a radiant heating stimulus. It has been claimed that FIR waves penetrate 3 to 4 cm deep into the peripheral tissues, but muscle temperature during FIR sauna bathing is unknown. The purpose was to quantify muscle temperature at three different depths during an FIR sauna session. Ten adults had a multisensor intramuscular temperature probe inserted into the quadriceps muscles before sitting in a FIR sauna for 45 min. Thermocouples were 3.4 cm (deep), 2.4 cm (middle), and 1.4 cm (superficial) below the skin surface. Muscle, core, and skin temperatures, and nude body weight (to calculate whole body sweat rate) were collected before and at the end of heating. Data are reported as (mean [95% confidence intervals]). Muscle temperature increased at the deep (+1.1 [0.3, 1.9]°C), middle (+1.9 [1.0, 2.9]°C), and superficial (+3.0 [1.8, 4.1]°C) depths (all
