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

backgroundLow cardiopulmonary fitness, measured by oxygen uptake peak (VO 2pk), is associated with postoperative complications and mortality. Obese people have difficulty in performing the cardiopulmonary exercise test, which requires maximal exertion. The incremental shuttle walking test (ISWT) and 6-min walking test (6MWT) have been used to assess cardiorespiratory capacity, mortality, and complications in the postoperative phase. However, the physiological response elicited by these tests in obese people is unknown. This study analyzed and compared cardiopulmonary fitness (oxygen uptake [VO2] and CO2 output [VCO2]) in the ISWT and 6MWT in obese adults using a telemetry system.

methodsFifteen obese patients (10 women; mean age 39.4 ± 10.1 years; mean body mass index 43.5 ± 6.8 kg/m(2)) with normal forced vital capacity (% FVC 93.7) performed the 6MWT and ISWT in the field in this cross-sectional study. Metabolic (VO 2pk, VCO2) and respiratory (minute ventilation; VE) variables were recorded using telemetry.

resultsObese patients performed the ISWT with an incremental and exponential cardiopulmonary response, with higher VO 2pk (15.4 ± 2.9 ml/kg/min), VCO2 (1.7 ± 0.7 l/min), and VE (51.4 ± 21.3 l/min) than the 6MWT (VO 2pk = 13.2 ± 2.59 ml/kg/min, VCO2 = 1.4 ± 0.6 l/min; VE = 41.2 ± 16.6 l/min (all p < 0.01). They also demonstrated more effort intensity, assessed by VO2, (p = 0.006) and heart rate (p = 0.04) in the ISWT than the 6MWT. In the 6MWT, patients showed a fast rise in ventilatory and metabolic response, reaching a plateau.

conclusionThe ISWT test generated superior metabolic and ventilatory stress than the 6MWT and may be more suitable for assessing cardiopulmonary fitness than self-paced tests.
