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

contextCold-water immersion (CWI) is the best treatment for patients with exertional heat stroke (EHS), and rectal temperature (Trec) cooling rates may differ between sexes. Previous authors have suggested that the body surface area (BSA):lean body mass (LBM) ratio is the largest factor affecting CWI Trec cooling rates in men with hyperthermia; this has never been confirmed in women with hyperthermia.

objectiveTo examine whether the BSA:LBM ratio and other anthropometric characteristics affect Trec cooling rates in women with hyperthermia.

designCross-sectional study.

settingLaboratory. PATIENTS OR OTHER

participantsSixteen women were placed in either a low BSA:LBM ratio (LOW; n = 8; age = 22 ± 1 years, height = 166.8 ± 6.0 cm, mass = 64.1 ± 4.5 kg, BSA:LBM ratio = 3.759 ± 0.214 m2/kg·102) or high BSA:LBM ratio (HIGH; n = 8; age = 22 ± 2 years, height = 162.7 ± 8.9 cm, mass = 65.8 ± 12.7 kg, BSA:LBM ratio = 4.161 ± 0.232 m2/kg·102) group. INTERVENTION(S): On day 1, we measured physical characteristics using dual-energy x-ray absorptiometry, and participants completed a maximal oxygen consumption test. On day 2, participants walked at 4.8 km/h for 3 minutes and then ran at 80% of their predetermined maximal oxygen consumption for 2 minutes in the heat (temperature = ∼40°C, relative humidity = 40%). This sequence was repeated until Trec reached 39.5°C. Then they underwent CWI (temperature = ∼10°C) until Trec was 38°C. MAIN OUTCOME MEASURE(S): Rectal temperature and CWI cooling rates.

resultsThe groups had different BSA:LBM ratios (P = .001), LBM (LOW: 45.8 ± 3.0 kg; HIGH: 41.0 ± 5.1 kg; P = .02), and body fat percentages (LOW: 25.7% ± 5.0%; HIGH: 33.7% ± 6.3%; P = .007) but not different BSA (LOW: 1.72 ± 0.08 m2; HIGH: 1.70 ± 0.16 m2; P = .40) or body mass index (LOW: 23.1 ± 2.1; HIGH: 24.9 ± 4.7; P = .17). Despite differences in several physical characteristics, Trec cooling rates were excellent but comparable (LOW: 0.26°C/min ± 0.09°C/min; HIGH: 0.27°C/min ± 0.07°C/min; P = .39). The BSA:LBM ratio (r = 0.14, P = .59), BSA (r = -0.01, P = .97), body mass index (r = 0.37, P = .16), and body fat percentage (r = 0.29, P = .28), LBM (r = -0.10, P = .70) were not correlated with Trec cooling rates.

conclusionsBody anthropometric characteristics did not affect CWI Trec cooling rates in women with hyperthermia. Therefore, clinicians need not worry that anthropometric characteristics might slow CWI treatment in women with severe hyperthermia.
