Predictors of mortality (Univariate analysis)

Variables	6MWD		FEV1/FVC		FEV1%		FVC%
Status	ALIVE	DEAD	ALIVE	DEAD	ALIVE	DECEASED	ALIVE	DEAD
Sample size	72	38	72	38	72	38	72	38
Lowest value	136	48	33	43	23	18	27	23
Highest value	585	382.7	106	122	138	111	130	116
Median	335	191.625	69	76	60.5	59.9	70	62.75
95% CI for the median	303.0000 to 361.9225	156.4968 to 224.5032	62.0000 to 76.7880	71.4968 to 89.0000	52.6360 to 68.0000	51.4968 to 71.5161	61.2120 to 76.1521	54.9936 to 71.0064
Interquartile range	261.3750 to 400.0000	150.0000 to 281.0000	54.0000 to 82.0000	68.0000 to 91.0000	39.5000 to 77.0000	47.0000 to 91.0000	57.0000 to 83.0000	52.0000 to 74.0000
p-value	< 0.0001	0.0098	0.6713	p = 0.1131

From this table, we can note that 6MWD, FEV1/FVC significantly predict mortality (p<0.05). Test applied was Mann-Whitney test and p-value was calculated by two tailed probability.
