title: Estimation of Multi-Treatment Effects from Observational Data with Application to Diabetes Mellitus [Methods Study], 2014-2021
title: Archival Version

description: Comparative effectiveness research compares two or more treatments to see which one works best for which patients. But patient traits, such as age or income, may affect patients' treatment choices. These traits may also affect patients' responses to treatments. As a result, researchers may have trouble telling whether a patient's traits, the treatment, or a mix of the two affected how well a treatment worked.
Statistical methods called matching methods can help address this problem when researchers use patient data to compare the effects of treatments. Matching methods help researchers find data from patients who had similar traits such as age or race and received different treatments. Because the patients are similar except for the treatment they receive, the differences in patients' health can more likely be credited to the treatment. Existing methods work well for comparing up to two treatments. But they may not work with three or more treatments.
In this study, the research team created two new matching methods to compare the effects of three or more treatments. The team then analyzed the new methods under different conditions to see how well each worked."
description: To develop two new matching methods and compare their performance with that of existing methods. The first objective aimed at development, testing, and guidance for estimation of effects of multiple treatment options that are either ordinal (eg, greater than or equal to 3 possible doses of a drug) or categorical (eg, greater than or equal to 3 possible drugs). Specifically, we will concentrate on different matching procedures. In the second objective, we use the developed methods to estimate the effects of multiple add-on, noninsulin antihyperglycemic treatments on major adverse cardiovascular events (MACE) or death.
description: The research team developed two new methods, basic matching (BM) and vector matching (VM), with variations that included

Choice of distance measure, such as the Mahalanobis distance, which tells researchers how similar patients are to each other
With or without caliper, a predefined threshold for distance when matching patients
With and without replacement of matched observations.

The research team first compared VM with three existing methods, GPS, SBC, and CRPM. They then compared BM and VM by conducting simulations with 3, 5, and 10 treatments. In each simulation, one treatment served as the reference treatment. The team looked at two outcomes for all comparisons:

The proportion of patients from the eligible population who received the reference treatment and were included in the final matched set
Standardized pairwise bias, which evaluates the quality of matches on each characteristic.

title: Replication data for: Peer Effects, Teacher Incentives, and the Impact of Tracking: Evidence from a Randomized Evaluation in Kenya

description: To the extent that students benefit from high-achieving peers, tracking will help strong students and hurt weak ones. However, all students may benefit if tracking allows teachers to better tailor their instruction level. Lower-achieving pupils are particularly likely to benefit from tracking when teachers have incentives to teach to the top of the distribution. We propose a simple model nesting these effects and
test its implications in a randomized tracking experiment conducted with 121 primary schools in Kenya. While the direct effect of high-achieving peers is positive, tracking benefited lower-achieving pupils indirectly by allowing teachers to teach to their level. (JEL I21, J45, O15)

title: Natural plankton respiration measured by INT reduction method from ice and interfacial samples collected during RRS Sir David Attenborough cruise SD035 in the Southern Ocean in February 2024 as part of the PICCOLO project .

description: Microbial community respiration (MCR) and the apportionment of this respiration to size classes is important for an understanding of the cycling of carbon through the marine foodweb and thus climate mediation. However, the proportion of MCR attributable to different size classes of plankton is not fully known. This dataset includes total and size-fractionated respiration rates determined as the production of formazan by the cellular electron transport system measured by the INT reduction method. Discrete interfacial seawater samples were taken from below floes 8 and 9 and ice samples were taken from free floating brown ice. These samples were taken by scientists from the University of East Anglia in February 2024 during the NERC-funded PICCOLO cruise SD035 in the Southern Ocean.

title: Replication Data for: What Can Dual Citizens Teach Us about Political Engagement?

description: While we witness historic changes taking place in the conception and practice of citizenship, we know little about the political consequences it may bring. What are the effects of citizenship, as a status and a process, on political engagement? To gain leverage in addressing this question, we draw on citizenship categories that combine birthplace and the number of citizenship held. We compare US-born dual citizens to both naturalized-dual citizens and US-born mono citizens, which allows us to distinguish between the potential effects of socialization and the additional legal status. The study analyzes two large nationally representative samples, presenting the first look at dual citizens in the United States. Results indicate that among dual citizens, those born in the US tend to participate more in politics than immigrants who naturalized. Among US-born citizens, the political participation of dual and mono citizens varies depending on the type of political activity. The study contributes to theoretical discussions on the relationship between an evolving citizenry and democratic participation.
