“…In the experiments with 50 minimum lethal doses of the infecting material there were several recoveries among those which received 0.001 to 0.002 to 0.003 gm., but all passed through a typical infection with all its symptoms. It is extremely doubtful, therefore, whether salvarsan or neosalvarsan mitigated the severity of the infection. …”

“…She had a weakly positive smooth muscle antibody and a positive ANA by CIA which was negative by HEp2 and therefore thought to be of doubtful clinical significance. She had normal complement, creatine kinase and CRP, and a low ferritin with low haemoglobin, in keeping with known iron-deficiency anaemia. …”

“…When there is poor response to conventional treatment, this should raise doubts regarding the diagnosis, and it would be prudent to consider a repeat biopsy as well as obtaining previous pathology specimens so that they can be re-reviewed. …”

“…Blood taken from the left ventricle at this time (at autopsy) also showed no precipitate in a large majority of cases; in eight experiments there was no precipitate, in three a doubtful trace of precipitate, and in one a definite small amount. …”

“…Stimulation of the splanchnic nerve in rabbits so frequently fails to produce results typical of direct constriction of renal vessels that we may regard the production of this effect in the two experiments in which this was done as doubtful. In the perfusion experiments by Richards and Plant (7) the reactions of the renal vessels to stimulation of the splanchnic nerve resembled those to intravenously injected adrenalin rather than to the direct excitation of constrictor fibers. …”

“…When any degree of sensitiveness has developed after the injection of immune sera, it has appeared late and has been of doubtful specificity. Conversely we have failed in any case to neutralize the activity of the active allergic constituents of bacterial extracts by incubation with any type of immune serum. …”

“…The basic requirement of my thesis was to develop a set of applications to improve the work of dis- tributed NA61/SHINE collaboration, the fact that there was no any doubts to choose the WWW technology proves that the World Wide Web is a great CERN's success story.…”

“…Concerning speed of recovery and return to work a trend towards more favourable results for the endoscopic procedures is noted. It is doubtful though, whether these results from the eleven and five years old studies are still valid for the more advanced procedures used today. …”

“…Gask L et al. (1998), in the pre-digital era, had discussed the application of video feedback (playing of recorded videos of patient consultations) of training in mental health skills to address areas requiring improvement(16), CVC which can be considered as an innovative digital module enables to provide real-time confidence maintaining feedback to the PCDs; thus the discordance of 17% also can be taken on a positive note as PCDs were able to identify their areas of error/doubts and bring it to discussion with tele-psychiatrist. …”
