Authors have noted that the correct pooled OR of the nine studies was incorrect. The corrected sentence in Abstract is as follows:
“The pooled OR of the nine studies was 1.29 (95% CI 1.14 to 1.47; p<0.001), of case–control studies 2.88 (95% CI 1.63 to 5.09; p<0.001) and of cohort studies 1.24 (95% CI 1.09 to 1.41; p<0.001), all of which indicated statistically signiﬁcant positive associations between job strain and hypertension.”
Also the pooled estimate from all studies in Results section under “Overall combined effect of job strain on hypertension” should be as follows “The pooled estimate from all studies showed a statistically signiﬁcant association between job strain and hypertension (OR 1.29; 95% CI 1.14 to 1.47) (see ﬁgure 3). The pooled estimate from case–control studies showed a positive association between hypertension and job strain (OR 2.88; 95% CI 1.63 to 5.09) (see ﬁgure 4).” Authors have supplied a modified figure 3, 4 and 5 as the result (See online supplementary 1, 2 and 3.)
Finally, the year of study number 8, Landsbergis et al, in table 1 should be 1994 instead of 2003. Similarly, the year of publication in the paper by Landsbergis should be 1994 instead of 2003. (see modified online Appendix 1).
