In this editorial, we discuss the current state-of-play of PROMs collection by kidney registries and provide an overview of what is (un)known about the feasibility and effectiveness of PROMs in CKD and other conditions. Read the paper at https://academic.oup.com/ckj/article/14/6/1495/6173985
SWEDEGENE was established in 2008 and currently contains DNA and information from about 2550 adults who have experienced specific ADRs, and from 580 drug exposed controls. Read the paper at https://www.nature.com/articles/s41397-020-0148-3
We identified 3 examples of suboptimal bias analysis, one for each common bias. For each, we describe the original research and its bias analysis, compare the bias analysis with good practices, and describe how the bias analysis and research findings might have been improved.

In this paper, we describe the use of the target trial framework for designing agent-based models when the goal is estimation of causal effects in the presence of interference, or spillover. Read the paper at https://academic.oup.com/aje/article/190/8/1652/6140873

To extend previous simulations on the performance of propensity score (PS) weighting and trimming methods to settings without and with unmeasured confounding, Poisson outcomes, and various strengths of treatment prediction (PS c statistic), we simulated studies with a binary intended treatment T as a function of 4 measured covariates.

Simulation is an important tool within epidemiology for both learning and developing new methodology. Unfortunately, few epidemiology training programs teach basic simulation methods. Read the paper at https://academic.oup.com/aje/article/190/8/1696/6140874

The benefits of using data from national registers as endpoints in epidemiological studies must be weighed against the impact of potentially decreased data quality. Read the paper at https://journals.sagepub.com/doi/full/10.1177/14034948211021191
Unmeasured confounding is a common threat to the validity of observational studies. In practice, confounding bias may arise from both confounders that are completely unmeasured and from confounders that are measured with error. Read the paper at https://academic.oup.com/ije/article/50/3/711/6048186

Immeasurable time bias exaggerates drug benefits in pharmacoepidemiological studies due to exposure misclassification arising from the inability to measure in-hospital medications in many health care databases. Read the paper at https://academic.oup.com/ije/article/50/3/987/6048410

Interrupted time-series (ITS) designs are a robust and increasingly popular non-randomized study design for strong causal inference in the evaluation of public health interventions. Read the paper at https://academic.oup.com/ije/article/50/3/1011/5937253
We report the current status of CKD registries in Europe in relation to their data collection on patients not on KRT so that in the future we may investigate to what extent also their data may be used for similar purposes, like collaborative research on CKD trajectories and patient outcomes.

The aim of this study was to explore the potential misclassification and evaluate the completeness of esophageal cancer diagnoses in the FCR and HILMO, considering misclassification. Read the paper at https://www.tandfonline.com/doi/full/10.1080/0284186X.2020.1792547
The term of overadjustment bias is used to refer to different scenarios. Here, we propose a unified definition of overadjustment, with four types. Read the paper at https://journals.lww.com/epidem/Fulltext/2021/09000/Revisiting_Overadju…

General population-based cohort studies provide solid evidence on mass Helicobacter pylori (HP) eradication effects. Self-reported questionnaires are occasionally used in such studies to ascertain the HP eradication history. However, reports on the reliability of these questionnaires are lacking.

A cardiovascular mortality algorithm applied to administrative health records had moderate validity when compared to vital statistics data. Substantial variation existed across study sites representing different geographic locations and two healthcare systems. These variations may reflect different diagnostic coding practices and healthcare utilization patterns. Read the paper at https://bmchealth
This commentary provides a practical perspective on epidemiological analysis within a single high-dimensional study of moderate size to consider a causal question. Read the paper at https://academic.oup.com/ije/article/50/3/1016/6140018
