These inconsistencies led us to reanalyze treatment outcomes in an expanded study group from the same clinical group. We found a striking inverse association between treatment latency and percentage of time ill before treatment ( rs=–0.67, N=376, p<0.0001) but no relationship to illness during treatment (rs=–0.03, N=376, p=0.51). That is, a shorter time to treatment was strongly associated with greater pretreatment morbidity. In turn, outcomes evaluated as change in percentage of time ill were inflated at shorter treatment latencies (rs=–0.55, N=376, p<0.0001). This effect no doubt contributed to an impression that earlier intervention yielded superior outcomes (1). Instead, this finding appears to derive from an association of a greater treatment-associated change with a greater level of pretreatment morbidity.
