“…As summarized in Supplementary File 5, one epidemiological study (Carandang et al 2011) and four clinical trials (Joseph et al 1996; Lee et al 2013; Mohiuddin et al 2007; Thomsen et al 2010) of patients provide information relating NRT and other SAHEs not generally related to cancer or CVD. Further details are presented in CAFs 28C, 30B, 32, 33 and 34.…”

“…The epidemiological study (Carandang et al 2011), in patients with subarachnoid haemorrhage, was ascribed study quality “fair”. Three clinical trials (Lee et al 2013; Mohiuddin et al 2007; Thomsen et al 2010) were ascribed a “high” risk of bias for only providing results for an intervention which included use of NRT (not necessarily in all patients), the results possibly reflecting possible effects of intervention rather than of NRT. The other trial (Joseph et al 1996), which did allocate patients to NRT, was ascribed risk of bias “low”.…”

We conducted a systematic literature review to identify and critically evaluate studies of serious adverse health effects (SAHEs) in humans using nicotine replacement therapy (NRT) products. Serious adverse health effects refer to adverse events, leading to substantial disruption of the ability to conduct normal life functions. Strength of evidence evaluations and conclusions were also determined for the identified SAHEs. We evaluated 34 epidemiological studies and clinical trials, relating NRT use to cancer, reproduction/development, CVD, stroke and/or other SAHEs in patients, and four meta-analyses on effects in healthy populations. The overall evidence suffers from many limitations, the most significant being the short-term exposure (≤12 weeks) and follow-up to NRT product use in most of the studies, the common failure to account for changes in smoking behaviour following NRT use, and the sparse information on SAHEs by type of NRT product used. The only SAHE from NRT exposure we identified was an increase in respiratory congenital abnormalities reported in one study. Limited evidence indicated a lack of effect between NRT exposure and SAHEs for CVD and various reproduction/developmental endpoints. For cancer, stroke and other SAHEs, the evidence was inadequate to demonstrate any association with NRT use. Our conclusions agree with recent statements from authoritative bodies.Electronic supplementary materialThe online version of this article (doi:10.1007/s00204-016-1856-y) contains supplementary material, which is available to authorized users.

“…12 Moreover, self-reported smoking cessation status is subject to misclassification. [26][27][28] Therefore, the usual IPW estimation based on (2) is challenged by the presence of covariate measurement error and outcome misclassification.…”

“…Our second example is on the study of the effectiveness of a perioperative smoking cessation intervention. 28 The data set contains the information of 168 patients on baseline covariates, including gender, age, BMI, the number of years of smoking, and cigarettes smoked per day as well as the treatment variable which is the indicator of taking or not taking the intervention. The outcome variable is the smoking cessation status for the previous 7 days collected at the 30-day follow-up postoperatively.…”

“…Preoperatively, self-reported smoking cessation data and exhaled .022 (−0.060, 0.027) (−0.059, 0.026 carbon monoxide (CO) levels were collected, with an exhaled CO level ≤ 10 ppm confirming the self-reported smoking cessation. 28 Among 146 patients whose exhaled CO levels are greater than 10 ppm, 11 individuals self-reported smoking cessation. If exhaled CO > 10 ppm is treated as a gold standard for showing the smoking status, then these preoperatively collected data yield an estimated misclassification rate,p 10 = 11∕146 = 0.075.…”

Weighted causal inference methods with mismeasured covariates and misclassified outcomes

Inverse probability weighting (IPW) estimation has been widely used in causal inference. Its validity relies on the important condition that the variables are precisely measured. This condition, however, is often violated, which distorts the IPW method and thus yields biased results. In this paper, we study the IPW estimation of average treatment effects for settings with mismeasured covariates and misclassified outcomes. We develop estimation methods to correct for measurement error and misclassification effects simultaneously. Our discussion covers a broad scope of treatment models, including typically assumed logistic regression models and general treatment assignment mechanisms. Satisfactory performance of the proposed methods is demonstrated by extensive numerical studies.
